...vacuum--ton one-billionths of an atmosphere--is one of the highest ever made in a a large container. Oil diffusion pumps produced it in the cyclotron's main chamber...
...this chamber that protrous are sent spinning at whirlwind velocities before they crash into fissionable material. However, all the air must be removed so that the protons will not collide with stray atoms in their path. This is the reason for the vacuum...
...With the vacuum equipment out of the way, the main job now is building and attaching the oscillator to the cyclotron. As the protons spin around, the oscillator boosts their speed each time they pass. These successive boosts often result in velocities greater than 10,000 miles per second...
