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]
This implies that the smaller the beam size at the interaction point, the faster the rise of the beta function (and thus the beam size) when going away from the interaction point. In practice, the aperture of the beam line elements (e.g. focusing magnets) around the interaction point limit how small beta star can be made.
One dimensional position-momentum plot, showing the beam ellipse described in terms of the Courant–Snyder parameters. In accelerator physics, the Courant–Snyder parameters (frequently referred to as Twiss parameters or CS parameters) are a set of quantities used to describe the distribution of positions and velocities of the particles in a beam.

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.
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.
Luis Walter Alvarez (June 13, 1911 – September 1, 1988) was an American experimental physicist, inventor, and professor who was awarded the Nobel Prize in Physics in 1968 for his discovery of resonance states in particle physics using the hydrogen bubble chamber. [1]
looking back it’s easy to see that New Year’s day in 1981 was really a turning point for us. It’s on this day that the Best Year Yet workshop was really born, although I didn’t start to lead the workshop for others until the following year. As we sat down to plan the coming year, common sense guided us to create this process.
Particle radiation is the radiation of energy by means of fast-moving subatomic particles. Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam. Due to the wave–particle duality, all moving particles also have wave character. Higher energy particles more easily ...
