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]
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).
The moving beam (also known as a projectile) consists of charged particles such as electrons or protons and is accelerated to relativistic speed. The fixed target can be a solid block or a liquid or a gaseous medium. [1] [2] These experiments are distinct from the collider-type experiments in which two moving particle beams are accelerated and ...
The KEKB accelerator was the world's highest luminosity machine at the time. [citation needed] A large fraction of the data was collected at the ϒ (4S). The instantaneous luminosity exceeded 2.11 × 10 34 cm −2 ·s −1. The integrated luminosity collected at the ϒ (4S) mass was about 710 fb −1 (corresponding to 771 million B B meson pairs).
The past is determined and stays what it was up to the moment T 1 when the experimental configuration for detecting it as a wave was changed to that of detecting a particle at the arrival time T 2. At T 1, when the experimental set up was changed, Bohm's quantum potential changes as needed, and the particle moves classically under the new ...
Lieutenant Colonel William Henry Rankin (October 16, 1920 – July 6, 2009) was the first person to survive a fall from the top of a cumulonimbus thunderstorm cloud. [1] He was a pilot in the United States Marine Corps and a World War II and Korean War veteran.
A second beam splitter: identical to the initial one. This beam splitter is positioned opposite the first, at the intersection between the lower path and upper path (after they have been redirected by the ordinary mirrors), at the exit of the box. A pair of photon detectors: located outside the box, they are aligned with the second beam-splitter.
The Bevatron was a particle accelerator — specifically, a weak-focusing proton synchrotron — at Lawrence Berkeley National Laboratory, U.S., which began operating in 1954. [1] The antiproton was discovered there in 1955, resulting in the 1959 Nobel Prize in physics for Emilio Segrè and Owen Chamberlain . [ 2 ]
