In particle accelerator: Linear electron accelerators The force that acts on electrons in a traveling-wave accelerator is provided by an electromagnetic field with a frequency near 3,000 MHz (1 MHz = 1,000,000 Hertz, or 1,000,000 cycles per second)—a microwave. The acceleration chamber is an evacuated cylindrical pipe that… Read More
history of particle accelerators
In particle accelerator: History …in California, constructed the first traveling-wave linear accelerator of electrons, exploiting microwave technology that had been developed for radar during World War II. Read More
linear accelerators
In linear accelerator Electron linacs utilize traveling waves rather than standing waves. Because of their small mass, electrons travel at close to the speed of light at energies as low as 5 megaelectron volts. They can therefore travel along the linac with the accelerating wave, in effect riding… Read More
synchrotron source
In spectroscopy: Synchrotron sources …synchrotron source consists of a linear electron accelerator that injects high-energy electrons into a storage ring (see particle accelerator: Synchrotrons). Since the intensity of the synchrotron radiation is proportional to the circulating current, many electron pulses from the injecting accelerator are packed into a single high-current bunch of electrons, and… Read More
use by Hofstadter
In Robert Hofstadter At Stanford he used a linear electron accelerator to measure and explore the constituents of atomic nuclei. At the time, protons, neutrons, and electrons were all thought to be structureless particles; Hofstadter discovered that protons and neutrons have a definite size and form. He was able to determine the precise… Read More
