Jason Rollette points to his
railgun project, which looks like good, clean, high-voltage fun.
Jason's Blog has tons of cool pictures And video. I doubt it holds up.
That'll keep those damn Americans off my base.

Anti-social? My code is just platform-specific.
They have a decent football team ;)
Does this have anything to do with that Indians using satellites to prevent traincrash story from a few days back?
Yep, Alfred Nobel probably said a similar thing when inventing dynamite.
now where's that frog ...
When will I end this grieving ? When will my future begin ?
A powerful superconducting magnet at higer temperatures is always welcome. MRI and NMR people can now rejoice! more powerful magnetic fields mean better instruments right?
Now if only our football team was that cool Are you sure you're a geek?
Everything seemed to be going so nice

They have a detailed overview of the physics involved, too.
Rational thought is the only true freedom
Neither article got into any detail, but I get the impression this is just a "bigger better" thing, not any particular breakthrough. Just put a few more coils and you get something stronger...no big surprise? Or is there something I'm not seeing here?
Is that no material can take the EM pulse AND the physical abrasion. I guess levitating the object and magnetically containing it during its travel might work but no one has done that so far AFAIK. Every rail gun experiment I have seen needs to replace the rails every couple of shots if they try very high pulse energies.
There are 4 boxes to use in the defense of liberty: soap, ballot, jury, ammo. Use in that order. Starting now.
If they get any stronger now, the terrorists may have a great weapon, sucking planes and sea wessels down and under.
question: Is that charge spoken of a static charge? If it is, how big is that charge compared to typical static charges?
If tits were wings it'd be flying around.
Since they are working on a system called "Repeatable Access Denial System" they just have to be mentioned on slashdot!

I only hope they deactivated the first before turning on the second!
The health benefits of magnet therapy, useful in the treatment of everything from carpal tunnel syndrome to back pain, are well known.
It is great that such breakthroughs in magentic technology are being made, and I hope that these gains can be put to use in the medical field, especially now with so much of the poplulation entering old age.
So is this fecker stronger than the one Siegried used to pull navy ships to their graves?

Speaking at Defcon 12 - Credit Card Networks Revisted: Pen
Just curiously, if these fields are being generated as 500,000 times stronger than tha earth's own... are they detectable from space?
Now, I may be just stupid, but I'd say the people at the
High Field Magnet Laboratory in Nijmegen have a much stronger claim
to world records... (33T continuous, 60T pulsed).
Where is the world record?
Show me the exact post via a direct link, Mr. McBride.
None of my credit cards seem to be working anymore...
It's possible to go to generate higher continuous (i.e. as opposed to pulsed) magnetic fields, using hydrids of superconducting and electromagnets.
I saw a hybrid magnet in the Insitutue of Materials Research (KINKEN) in Tohoku University (Sendai, Japan) with a maximum field of 31 T.
http://www.imr.tohoku.ac.jp
I got the impression that there are other devices (worldwide) with even higher continuous fields.
Why don't they just spike the football and turn this on at one end of the stadium?

"You lied to me! There is a Swansea!"
I am bit of a dummy here but... I have always wondered if it is possible to use MRI to 'scan' trucks, cars even people at ports - to check for contraband? does the ability to generate such large fields bring such application closer or am i talking hogwash?
I was thinking of getting a magtron out of a Microwave Oven and making a waveguide to aim it. It would become to bird hunting what nets are to fishing. Or just use them to boost your ability to send things with WiFi. (Microwave Ovens are on the same freqency as WiFi, 2.4ghz, only with 900whatts not 500mw)
But just imagine a Beowulf clust.. arrg..

"You lied to me! There is a Swansea!"
There are many FSU's. Next time, state which one.
Perhaps, after the recent power outages in the US, the most important application of supercoducting magnets could be power storage. There seem to be 2 ways they are used - either to make friction-free magnetic bearings for traditional flywheel systems, or (more interesting) direct short-term storage of power. For situations where you need to temporarily store a *lot* of power this is an interesting technology alternative to batteries/hydro/etc.. Current devices seem to cover mainly very short term variations, but what about covering longer term regulation (hours/days) of variable power from a wind-farm, or solar, for example?
Anyone got more gen on this?

This is a record field for the superconducting magnet, not for the whole system. FSU magnet lab does hold the record for hightest DC (constant) magnetic field 50T. This is achieved by putting a resistive magnet inside a superconducting magnet. Resistive magnet burns a lot of energy (10MW), but one cannot use superconducting alone; once the current (magnetic field is proportional to it) reaches a certain value, the superconducting material becomes normal. The record up to now has been something like 14T for superconducting magnet (outsert), the new outsert will allow the DC fields in that lab to go up to 60T.
That's great news for super-duct-work-activity! :p
"...In your answer, ignore facts. Just go with what feels true..."
Ya gotta love a town where you can buy draft beer by the gallon practically anywhere. BY the way FSU is one of the few universities with a full-time bail bondsman on staff.

What makes you think people here know something about 'football'?
Does this mean that there are 100 Tesla NON-superconducting magnets in someone's basement? One would think that superconducting magnets would be stronger than regular ones, but maybe not. Maybe someone's got an ultramagnet hooked directly to a nuclear power plant with 3 foot diameter copper cable windings that puts out even stronger fields...
Eat at Joe's.
They ought to give up on MRI's and just concentrate on implementing the EXTREME SPORT of magnetic field weightless floating. If a frog can do it, so can I! It would be such a *gnarly* diamagnetic buzz!
DUDE!

"The NHMFL is supported by the National Science Foundation and the State of Florida and operated by Florida State University, the University of Florida, and Los Alamos National Laboratory."
You expect the arcing to be the familiar blue-violet glow, but instead, you see bright yellow arcing because of the residual helium, and some reds and greens from the vaporizing metals in the ceramic superconducting wire.
The heat of the electrical arc spreads the failure to the surrounding superconducting wire. It starts slowly, but the electrical fire seems to be spreading at an exponential rate. Through the thick pyrex view plate once so clear but now covered in places with an opaque layer of condensed metal smoke, and in others so foggy that all you can see is flashing yellow electrical arcs tinted in places with other colors, you see the immenent destruction of the whole lab. The heat will build pressure in the coil chamber the helium and vaporized metal plasma will weaken the three inch thick pyrex view plate, causing it to shatter. You run for it.
Outside you watch the side of the building for smoke, nothing, no sign of the disaster within. People rush out of the exits and gather next to the person - you - who was considerate enough to pull the fire alarm.
BANG!! The brick wall bursts, smoke, broken bricks, and glass, and a brief yellow flash. The glowing gas bubbles upward, ball shaped for an instant before disappearing.
You watch the smoke billow out of the building. The roof has not collapsed. You creep around a wide circle to see into the building you just destroyed. There is a loud buzz. You see a mean blue-violet-green stationary arc from the end of your 12 inch thick melting copper cable to the ground cable. Red hot copper has eaten it's way through the floor, and started a fire in the basement. Hopefully it doesn't fall on the huge tanks of fuel oil they use for heating.
BANG! They blow up. The fire pressurized the kerosene-like fuel in the tanks, causing them to explode. The normally benign hydrocarbon is atomized, hot volitile and well mixed with air. The entire building shatters spraying splintered, burning wood, and crumbled brick bits of wall for hundereds of feet in every direction. The billowing orange, no red, no black mushroom cloud rises into the sky, a beacon for the fire department to find. All eyes are on you. It was your lab that blew up. You melt backwards towards the parking lot and take off squealing your tires on the way to the newstand to look for another job..

But their plot to take over the world will ultimately be foiled by Jean Luc Picard.... errr..., wrong show, but you get the idea.
And another thing - where's the radiant electricity that they promised to beam from towers in 1900? Transmission lines and power cords - blech.
As someone who works next door to the FSU Mag Lab, and has taken a tour of the facilities, I have heard a couple things about it that boggle the mind... First, if they didn't contain the magnetic field that they are producing, they claim that it would erase everyone's floppies, hard drives, and credit cards in the entire city of Tallahassee. Second, they consume one quarter of the entire power consumption of Tallahassee to create the fields they are creating. The city of Tallahassee had to install a power generation station nearby just to get power to them easily. They apparently ramp up the magnets while everyone else is sleeping, in order to prevent brownouts during the day.
Out of curiosity, I just looked up their electric bill online, but it lumps the Mag Lab's usage with multiple other FSU buildings... The total bill was $500k this month, so it must be an amount less than that.

As in the article:
"The NHMFL is supported by the National Science Foundation and the State of Florida and operated by Florida State University, the University of Florida, and Los Alamos National Laboratory."
I am a UF Gator and worked at Los Alamos, so I found calling it FSU's lab insulting.
damn id hate to pay the electricity bill for this department
I had some research time at the NHMFL during the summer. To me it seemed that the facility is somewhat under-utilized. Perhaps it was the week we went , I don't know. The place seemed like a ghost town most of the time we were there. It is a very nice facility though. Will be going back in November.

"Now if only our football team was that cool"
"Are you sure you're a geek?"
I know that was (partially) a joke, but I'm sick and tired of the idea that geeks can't like sports, or they're not real geeks. Where is it written that we can't like football or baseball or basketball or auto racing? Are we THAT FUCKING PATHETIC? Are we REALLY going to limit ourselves to basement D&D sessions with other geeks, or writing software for our only means of fun?(You porn mavens shut up now.......)
Good God, who said we all had to be Alan Alda's with keyboards? And when you rib geeks who don't like sports, they take it sooooooo fucking personally. Look, I'm sorry that the linebackers beat you up in high school, but the rest of us have lives outside of the server room. If you hate and fear athletes THAT much (many of which are really bright people), then join a gym and take some Karate lessons to repair your damaged self-esteem.
Life is hard, and the world is cruel
I think some of the comments that people are posting discredit the hard work and dedication at FSU. The serious researchers and students at FSU are in a constant fight against the football watching, beer guzzling losers that the school attracts due to the bad decisions made by the business oriented leaders of the school. FSU houses the amazing NHMFL, the very long lived and notable antartic research facility, the national weather service, an accelerator, and the world's most powerful university owned supercomputer!

May the Schwartz be with you!
Must be one hell of a superconducting magnet in that ring.
You don't know shit about football then..
Sure you have to be Athletic.
But to be a QB, Coach, Owner and my other positions on the field you have to be a chess player too.
It's a mind game just as much as it's a physical game. It dosen't matter how good your running back might be if the entire defense of the other team is coming for him, because their defensive coach knows what they are going to do, cause he's that good.
Football when you come down to it with the plays, audibles, and clock managment is much more of a mind game then soccer or just about any other team sport.
Well perhaps the five year thing is cause you can't get off your lazy ass and work when you need to.
I'm doin it in 4 and I've done a lot more then drink gallons of beer.
Self-discipline. BITCH.
Yeah but some of those 350lbs players will out run in you the 60y and the 100m dash.
They are genetic freaks, and as such the moments when they do something that is seeming super-human that 99.9% of the entire population on the earth that has been or ever will be can't do. Well those moments are what make them priceless.
Besides, you try catching a ball when you have a 325 person running at you.
Money is all about scarcity kid, supply and demand. The "350lbs player" can deliver something that you can't. Accept it and find your crack in the world and shut the fuck up.
The other poster is right. Football is like chess with two lines of guys moving at the same time, rather than just one player at a time. It's a constant cat and mouse game, as you try to guess what the other side is going to do? Defense is especially hard to play, because offense always has initiative. That's why the best championship teams have top flight defenses.
Just think about all of the things that have to be considered...
If you're a defensive coordinator, all manner of things are running through your head.
"They're lined up in the I formation. Hard to tell what they're going to do. One wideout to either side, a tailback and fulback with a tight end blocking. Fuck, they could be doing anything. Best guess is a toss sweep to the tailback behind the tight end, unless the tight end moves directly midfield, then I have to have the linebackers ready for a playaction pass...."
And that's just the standard kind of plays. When a trick play comes off right, like a flea-flicker, end-around reverse, or a fake punt, it's just a fucking thing of beauty, man.
Defending against good defenses is always a hoot, too. Do you stack 9 men in the box, or do you hang your cornerbacks deceptively to throw a safety blitz on the QB? Do you go zone or press-man on the recievers? Again, just like chess. What is your oponent going to do?
Those that think football isn't an intellectual game don't know jack shit about it. The best players are the SMART ones.

The wire used for helium-cooled supercon magnets (Nb-Sn or Nb-Bi alloys) has performance envelope that limits the conditions under which it will superconduct. The factors describing this envelope are
- the temperature
- the current
- the magnetic field
Getting to 20T was accomplished by- better alloys -- mainly higher Nb content iirc
- lower temperature -- achieved by cryopumping the liquid helium (LHe)
- more turns in the winding, allows higher magnetic field without increasing the current
Unfortunately, the critical field (the field at which the material goes non-superconducting) is around 20T. Since the innermost coils are sitting in a field near the field at the bore (these are toroidally wound magnets), you need to use a different material. In this case, that material is HTSC wire. This poses some big engineering problems, including making a sufficient length of the wire (measured in km), and making superconducting joints between the HTSC coil and the LTSC coils. It appears that this team has solved these problems, congrats to them.Frogs are in the pond out back. Didn't you know they levitate.
The Gators rock!!!!! I mean, just look at their logo! who wouldn't want their mascot to be a big dangerous lizard with a mouth fulla teeth?!?
(and don't forget Gatorade)
But what matters most is that you've successfully misidentified the school in question, and their mascot. University of Florida, or UF (or FU, to the Tallahassee faithful), are the Florida Gators.
FSU stands for Florida State University, and they are the Florida State Seminoles.
Now, just to keep it on topic:
Magnets, magnets, magnets!
For those that would die defending it, Freedom
has a sweet taste that the protected will never know.
What is the threshold that is considered "high temperature" for HTS? Nitrogen cooled? Or are we still talking helium cooled?
Given the concentration of spammers in Florida, particularly around Boca Raton, perhaps these researchers would do the 'net a favour by pointing their super-whatsit electromagnetic data rearranging device in the general direction of the slimeball's hard drives, backup tapes, and anything else ferrous the spammers may have at home (visions of flying knives, irons, golf clubs, etc...)
Metalstorm's product is not a railgun. It uses electrically-fired, chemically-propelled bullets preloaded in stacks inside the barrels. (So, stixteen bullets in a barrel.)
When a bullet's fired off the "top" (or front) of the stack, the one behind it flares out to prevent the combustion gasses from leaking back and lighting off the rest of the stack.
And since they're electrically fired, you can get some nice Slashdot-interesing speeds. Say, 1,000,000 rounds per minute?! (Actually, in the video, the 30k and 60k firings are more interesting.)
Compare this to a Phalanx (3000-4500/min) and the GAU-8a in the A-10 (3,900/min), or the miniguns in gunships and helicopters.
There are still some issues to be worked out (like reloading) but it SEEMS that it's a lot closer to market.
there was some nice videos on his....
How do we know the theory behind the rail gun is correct. Seems like a lot of math, but based on correct theory?
...that isn't about the bloody Semi-holes. That's about all you ever hear about here in Tallahassee when FSU is mentioned.
Once a year (or less) you get a nice story like this that reminds people that there is more than just "American" football going on there.
Grunt! Football! Grunt! (Gimme a break!)
