A very large team of researchers linked to several institutions in China and Japan has measured the highest photon ever recorded. In his article published in the journal Physical Review Letters the group describes their research into the data from the Gamma cooperation of the Tibetan air and what they have discovered.
Gamma Collaboration in the Tibetan Air Show is an observatory on the Tibetan Plateau and the people who run it. It consists of 600 particle detectors built on 65,000 square meters of land. His goal is to find subatomic particles emanating from space. The detectors observe debris from photons that face particles in the Earth's atmosphere and cosmic rays, which are primarily protons and atomic nuclei. Team members with this new effort were focused on photons that head to the Earth from distant places. In order to measure them, the researchers excluded the detection of the muon, leaving only particles associated with the photon collisions. Researchers have been able to calculate the energy of a given photon using particle data that they have hit. one of which registers 450 TeV. These finds represent the first measurements of high-energy photons above 1
