particle physicists Particle physics or high-energy physics is the study of fundamental particles and forces that constitute matter and radiation. The field also studies combinations of elementary particles up to the scale of protons and neutrons, while the stud ...

It was built and operated by physicists from many countries, including: the USA, Japan, South Korea, China, and the Philippines. For tracking charged particles, the detector contained an Inner Tracking Chamber and a Central Drift Chamber. A novel

X-ray detector X-ray detectors are devices used to measure the flux, spatial distribution, spectrum, and/or other properties of X-rays. Detectors can be divided into two major categories: imaging detectors (such as photographic plates and X-ray film (photograp ...
