(Berkeley Lab)   While everyone is distracted by the LHC, physicists in California are working on particle accelerators small enough for fit in your hand. Now would be a good time to apologize for the wedgies you gave them   (newscenter.lbl.gov) divider line 26

See folks? When you defund science in this country you force people to innovate! It's a win-win!

Egon is slightly impressed. Not enough to offer you a Baby Ruth, but impressed.

Looks like the coaxial cable splitters I have in my basement! Some patent troll will probably sue them for stealing their design asthetics.

For cripes' sake, green plasma?

Is that an accelerator in your pocket or are your electrons just excited to see me?

Hell you can get one for $500 already if you know where to look...

They had ones small enough to fit in a backpack in the 80s.

"N-Filter"? Are you telling me the damn thing is racist to boot? Hope Winston wasn't around for the first test run before they installed that...

It's LBNL. If they've got a small accelerator, you have to look past the dual-use part.

Ok. A bit of arcane history. There are ALREADY "tabletop accelerators", just not this sort. They're a bit bigger than the photo. They're tiny little self-contained cyclotrons, they accelerate nuclei, and in the real world, they'd work once. They slam deuterium nuclei into a beryllium target, producing a nice burst of neutrons, just what you'd want in a nuclear weapon for an initiator.

THIS guy, it accelerates electrons. Over 200MeV, you can slam those into a film of uranium (maybe tungsten, but uranium works better) and you'll get a burst of neutrons, too. Only this thing, properly modified, gives you very tightly timed, very compact bursts of neutrons with precise timing. WAY better than you can get from a zipper. Even if it's fewer total neutrons, you get them all in one tiny packet, so, the total neutron initiation of a supercritical assembly would be higher than with a bigger sloppier drawn out burst from a zipper or neutron tube. Only with this thing, no replacing neutron tubes as the tritium decays.

How long until they discover the uselesson or the wasteon or the pointlesson?

Oh, that's right...they've been doing that the whole time.

Good, not enough people understand the history of technology.

Every CRT is a particle accelerator, and if you crunch one open in a vise, you can hold the gun in your hand.

Quantum Apostrophe: Every CRT is a particle accelerator, and if you crunch one open in a vise, you can hold the gun in your hand.




AFTER releasing any residual charges in the tube (color CRTs can have up to 26,000 V stored. Low amps, so it most likely won't kill you unless you're standing in water or leaning your naked arm across a grounded metal pipe, but it sure won't feel too nice), and breaking the seal on the tube to let air in. Throwing rocks (or shooting) at it from a distance would be more fun (and likely safer) than a pair of pliers or hammer. Wear safety goggles and gloves when dealing with glass CRTs.

Wait a minute... so is this something that can be used as a trigger for nuclear weapons? Granted, nuclear weapons are old tech these days, but certain people are still very touchy about proliferation of the underlying technology.

Good thing Iran isn't on the internet.

I have it on good authority Iran's design still uses polonium.

Anyway, the trigger's a different part. Configured properly, this is a really nice initiator. Somewhat smaller than a zipper, no maintenance.

Don't worry, I haven't done an in-depth design discussion since the really nice one on new tech explosive drivers that got deleted from Fark in 2004. Same weapon series by the way.
