The Housekeeping subsystem of the JEM-EUSO instrument

摘要

The JEM-EUSO instrument is a refractive telescope being proposed for attachment to the Japanese Exper-imentModule, Kibo, onboard ISS. The instrument is substantially complex, including large Fresnel lenses, an focalsurface covered by 4932 MAPMTs of 64 pixels, atmospheric monitoring subsystems (IR camer and LIDAR), low andhigh voltage power supply subsystems, tilting mechanism and a lid. All these subsystems must be turned on and off andmonitored, and telemetry has to be conveyed between them and the principal CPU. The housekeeping subsystem (HKSS)is in charge of those tasks. In this contribution we describe the requirements and design of the JEM-EUSO HKSS.
