The cooling design scheme for the SiPM camera of the LACT experiment
Abstract The LACT experiment will construct 32 six-meter aperture imaging atmospheric Cherenkov telescopes at the LHAASO site for in-depth observation of the ultra-high-energy gamma-ray sources discovered by the LHAASO experiment. The telescope mainly consists of three parts: a support and rotation system, a reflector, and a silicon photomultiplier (SiPM) camera. The SiPM camera is composed of 1616 SiPM sensors connected to 1616 channels of readout electronics. This paper reports on a cooling scheme suitable for the SiPM camera's all-sky rotational working posture in a high-altitude environment, and the effectiveness of the cooling system is verified through thermal simulations and laboratory measurements.
