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 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.
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 travel time of the neutrinos had to be measured by tracking the time they were created, and the time they were detected, and using a common clock to ensure the times were in sync. As Fig. 1 shows, the time measuring system included the neutrino source at CERN, the detector at LNGS (Gran Sasso), and a satellite element common to both.
Einstein proposed such a test in the paper where he first stated the equivalence of mass and energy, mentioning the radioactive decay of radium as a possibility. [35] The first test in a nuclear reaction, however, used the absorption of an incident proton by lithium-7, which then breaks into two alpha particles. The change in mass corresponded ...
In order to create antiprotons (mass ~938 MeV/c 2) in collisions with nucleons in a stationary target while conserving both energy and momentum, a proton beam energy of approximately 6.2 GeV is required. At the time it was built, there was no known way to confine a particle beam to a narrow aperture, so the beam space was about four square feet ...
