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]
While using a recirculating charged particle beam with a magnet lattice resembling that of a storage ring, each particle travels through the recirculating arc before being decelerated in a linac structure. The same linac structure also accelerates new low-energy particles that are continuously injected into the linac.
2007 ISO radioactivity danger symbol intended for IAEA Category 1, 2, and 3 sources defined as dangerous sources capable of causing death or serious injury [1]. This article lists notable civilian accidents involving radioactive materials or involving ionizing radiation from artificial sources such as x-ray tubes and particle accelerators.
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).
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.
The combination of beam conditioning devices controls the thermal load (heating caused by the beam) at the end station; the spectrum of radiation incident at the end station; and the focus or collimation of the beam. Devices along the beamline which absorb significant power from the beam may need to be actively cooled by water, or liquid nitrogen.
James Benjamin Rosenzweig is a experimental plasma physicist and a distinguished professor at the University of California, Los Angeles (UCLA). [1] In the field of plasma wakefield acceleration, he is regarded as the father of the non-linear "blowout" interaction regime, where a laser beam, when fired into a plasma at intense levels, expels electrons from the plasma and creates a spherical ...
This is necessary when, for example, a circular particle accelerator has to be shut down. Dealing with the heat deposited can be an issue, since the energies of the beams to be absorbed can run into the megajoules. [3] An example of a charged-particle beam dump is the one used by CERN for the Super Proton Synchrotron. Currently, the SPS uses a ...
