Columbia Holds Wake For Historic Cyclotron 72
Pickens writes "They called it leviathan, behemoth, Big Bertha. At 12 feet wide, rising 7 feet above the cement floor and weighing an estimated 65 tons, the Columbia cyclotron, the particle accelerator built in the late 1930s by Columbia physicist John Dunning, played a crucial role in the dawn of the nuclear era. Dunning's experiments verified fission, established many of its properties, and, most significantly, demonstrated that the rare isotope Uranium 235, and not the more common U-238, was the more fissionable form of the element. 'In a week or two, they will dismantle it, and they will sell it for scrap,' says George Hamawy, Columbia University's director of radiation safety. 'This is the last chance to see it,' Hamawy added as students held a wake and contractors arrived to remove the cyclotron. 'We're going to make two-thousand-pound sections,' said one contractor before taking the cyclotron's measurements. 'We'll start slicing on Monday.'"

I heard an interesting anecdote about the picture you occasionally see of its operators (a dozen young women, sitting on stools, in front of analogue instrument panels). Apparently, they were completely in the dark about what this facility was doing, but sat there all shift staring at gauges and what-not with instructions to inform a supervisor if something exceeded a given limit.

Look, the Navy has all this romantic imagery associated with plying the seas in deadly warships (read "Choosers of the Slain" by Kipling) but almost all ships end up as razor blades or sunk for target practice. Likewise a lot of us have fun tinkering with computers...but over the past 5 years haven't we all broken down and rebuilt assorted Frankenboxes for this project or that project a hundred times over?
It's the adventure of DOING stuff with the things that is important, not the things themselves. As impressive as the cyclotron is, it's the science and discovery that are really meaningful.
Re:It was always disposable (Score:4, Insightful)
The things are important because they provide a tangible link between the events they represent and people who weren't present for them. I wasn't even born when the XB-70 program was underway, but when I visited the Air Force Museum and saw the one remaining prototype, it made all of the things I'd read about it more real to me. None of us (other than the vampires) were alive when the ancient trading routes in the Black Sea were in use, but the artifacts discovered there by Robert Ballard help us understand more about them.
Obviously some things aren't practical to keep around - fleets of obsolete aircraft carriers, for example. But a single cyclotron? What's so important that they need to put in its place?

The largest [wikipedia.org] Cyclotron ever built has a main magnet with a field strength of 0.46 T.
The magnets in your speakers have a field strength of about 1T. Your hard drive probably contains a 1.5T magnet as well.
An NMR (MRI) machine will range from anywhere from 1.5T to 7T (although experimental setups can go a good bit higher [wm.edu]).
The strongest continuous magnetic field produced in a laboratory is 45T.
The strongest pulsed magnetic field ever created was by the Russians at 2,800T (they cheated and used explosives).
The reason the magnet is so "huge" is that the field needs to cover a large area.

assuming you get the beam focussed after filament replacement, etc, the only danger to anything except credit cards, people standing between loose steel and the moosey magnet, etc. is behind the target window in the chamber casting.

this is why stuff like this is built underground with no easy access. Mother Earth is your shield, suffering those protons and (later) neutrons for you.
