Description

Wide-field Imaging Cherenkov Telescopes Array (WFCTA) is one of important detectors for the Large High Altitude Air Shower Observatory (LHAASO). Since the optical system of each telescope is reflective type with comparable smaller F-number, the acceptance angles of converging light on the focal plane are markedly large meanwhile present complicated distribution. We design and optimize a square light concentrator to improve the camera’s photon collecting efficiency and eliminate the dead zone between the photomultipliers on the camera. Moreover, the performances of this optical component for ultra-high energy cosmic ray Cherenkov events are investigated.
