Visible-light photon counter

From Wikipedia, the free encyclopedia

VLPC stands for visible-light photon counter and refers to a new high quantum efficiency multi-photon counting detector, which operates at visible wavelengths. The ability to be capable of counting the exact number of photons that are detected is extremely important for QKD. The device is being used extensively in the central tracking detector of the D0 experiment, and for muon cooling studies for a muon collider (MICE).
