  2. Klystron - Wikipedia

    en.wikipedia.org/wiki/Klystron

    The Varians went on to found Varian Associates to commercialize the technology (for example, to make small linear accelerators to generate photons for external beam radiation therapy). Their work was preceded by the description of velocity modulation by A. Arsenjewa-Heil and Oskar Heil (wife and husband) in 1935, though the Varians were ...

    en.wikipedia.org/wiki/Varian_Associates

    Varian Associates was one of the first high-tech companies in Silicon Valley.It was founded in 1948 by Russell H. and Sigurd F. Varian, William Webster Hansen, and Edward Ginzton to sell the klystron, the first vacuum tube which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.

  4. Linear particle accelerator - Wikipedia

    en.wikipedia.org/wiki/Linear_particle_accelerator

    As linear accelerators were developed with higher beam currents, using magnetic fields to focus proton and heavy ion beams presented difficulties for the initial stages of the accelerator. Because the magnetic force is dependent on the particle velocity, it was desirable to create a type of accelerator which could simultaneously accelerate and ...

    It was decided to build a new linear accelerator, since the old Linac was unable to keep up with the technical advances of the other machines within CERN's accelerator complex. Linac 2 replaced the Linac as CERN's primary source of proton beams in 1978. It kept the same beam energy of 50 MeV, but allowed for more intense beams with beam ...

    Linear accelerator Animation of the operation of a medical use linear accelerator. The French company CGR manufactured the Neptune and Sagittaire linear accelerators.. In the early 1970s, CGR and the Canadian public company Atomic Energy of Canada Limited (AECL) collaborated on the construction of linear accelerators controlled by a DEC PDP-11 minicomputer: the Therac-6, which produced X-rays ...

    Fermitron was an accelerator sketched by Enrico Fermi on a notepad in the 1940s proposing an accelerator in stable orbit around the Earth. The undulator radiation collider [7] is a design for an accelerator with a center-of-mass energy around the GUT scale. It would be light-weeks across and require the construction of a Dyson swarm around the Sun.
