...times as great as that of an electron; by the end of an accelerator experiment, says Livingston, an electron may become "over 6 times as heavy as a proton." In other words, the mass of the electron is increased 12,000 fold; thus, Livingston notes, many physicists half-seriously call the machine a "ponderator...
...present, Preston says, the Harvard machine can be considered an "intermediate energy cyclotron;" there are about half a dozen larger accelerators of this type in the world. Beyond a certain level of energy (about 600 million electron volts), he says, this particular type of machine (utilizing a single large magnet) is no longer practicable, because of the large size of the magnet required. Therefore, new methods involving a series of magnets, such as those used in the Cambridge Electron Accelerator and the Brookhaven cyclotron, had to be devised...
