Thought there will be no celebration, tomorrow will mark an anniversary, Two years ago, with humming, crackling, and much publicity, Harvard's brand new cyclotron first went into action. This 125,000 volt particle pusher is the core of a new set of buildings on Oxford Street which comprises the Nuclear Laboratory...
This turned out to be a break for physicists in general because the new cyclotron filled a gap in their tool-chest. Cyclotrons are used to bombard target material with particles traveling at different rates of speed. To get a whole range of speeds, physicists need several cyclotrons of different power. Before the new Harvard cyclotron appeared, there was only one very powerful mode--the 400,000,000 volt job owned by the University of California--and quite a few smaller ones of not much more than 30,000 volts. The Harvard cyclotron helped to provide the much wanted middle...
...cyclotron was also a break for Harvard physicists in particular because they got a new laboratory in the deal. the University supplied $500,000 to set up on Oxford Street a two-story brick building, complete with ivy, office space, research rooms, and a machine shop; a connecting passage, and a windowless gray structure to house the cyclotron...
...foundation under the gray building is dirt and concrete 15 feet down. All the walls are filled concrete--the outer one three feet thick and the inner one, surrounding the cyclotron, six feet thick...
Anyone who wants to get at the cyclotron for minor repairs can go through a small seven-ton door in the inner wall. For a major overhaul the maintenance crew can open the two 110 ton doors at the West end or the two 60 ton ones at the East end. These slabs are pushed back and forth on roller tracks by a large crane hitched to the ceiling. The total shielding around the machine amounts to some 600 cubic yards of concrete and 34,000 pounds of structural steel...
