Anatoli Petrovich Bugorski (Russian: Анатолий Петрович Бугорский; born 25 June 1942) is a Russian retired particle physicist. He is known for surviving a radiation accident in 1978, when a high-energy proton beam from a particle accelerator passed through his head. [1] [2]
Teleforce was mentioned publicly in the New York Sun and The New York Times on July 11, 1934. [9] [10] The press called it a "peace ray" or death ray.[11] [12] The idea of a "death ray" was a misunderstanding in regard to Tesla's term when he referred to his invention as a "death beam" so Tesla went on to explain that "this invention of mine does not contemplate the use of any so-called 'death ...
An energy recovery linac (ERL) is a type of linear particle accelerator that provides a beam of electrons used to produce x-rays by synchrotron radiation. [1] First proposed in 1965 [ 2 ] the idea gained interest since the early 2000s.
The Therac-25 is a computer-controlled radiation therapy machine produced by Atomic Energy of Canada Limited (AECL) in 1982 after the Therac-6 and Therac-20 units (the earlier units had been produced in partnership with Compagnie générale de radiologie (CGR) of France).
Particle therapy is a form of external beam radiotherapy using beams of energetic neutrons, protons, or other heavier positive ions for cancer treatment. The most common type of particle therapy as of August 2021 is proton therapy .
A particle beam is a stream of charged or neutral particles.In particle accelerators, these particles can move with a velocity close to the speed of light. [1] There is a difference between the creation and control of charged particle beams and neutral particle beams, as only the first type can be manipulated to a sufficient extent by devices based on electromagnetism.
Acceleration of a primary proton beam in a particle accelerator. Proton beam collision with a fixed target. In such a collision secondary particles, mainly pions and kaons, are produced. Focusing, by a set of magnetic horns, the secondary particles with a selected charge: positive to produce the muon neutrino beam, negative to produce the muon ...
In response, a local technician was called in to repair the device, but was unable to do so, and in fact caused further damage. Subsequently, competent authorities were notified, but as the apparatus had been tampered with, they were unable to ascertain the exact doses of radiation received by the patients (localized doses might have been in ...
