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]
Wheeler's cosmic interferometer uses a distant quasar with two paths to equipment on Earth, one direct and one by gravitational lensing. After [2]. In an attempt to avoid destroying normal ideas of cause and effect, some theoreticians [who?] suggested that information about whether there was or was not a second beam-splitter installed could somehow be transmitted from the end point of the ...
A fixed-target experiment in particle physics is an experiment in which a beam of accelerated particles is collided with a stationary target. 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 ...
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).
Albert Stevens (1887–1966), also known as patient CAL-1 and most radioactive human ever, was a house painter from Ohio who was subjected to an involuntary human radiation experiment and survived the highest known accumulated radiation dose in any human. [1]
The second phase of the treatment was abandoned on medical advice, and Norris survived for some time after the overdose. January 23, 2008 – A licensed radiology technologist, Raven Knickerbocker, at Mad River Community Hospital in Arcata , California performed 151 CT scan slices on a single 3 mm level on the head of a 23-month-old child over ...
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.
Belle II is a general purpose high-energy particle detector with almost full solid angle coverage. It has a cylindrical shape to cover the e + e − collisions happening on the central axis of the detector. The detector is asymmetric in beam direction, because the initial energy of the electron beam is larger than the positron beam.
