[CRI131] KLYPVE-EUSO photodetector design: focal surface and data processing system
KLYPVE-EUSO is a recent modification of the mirror-type UHECR space observatory for the Russian Segment of the ISS proposed by SINP MSU in 2010, which was developed by the JEM-EUSO collaboration. A Schmidt type optical scheme was adopted in 2016 as a baseline solution, doubling the exposure of the detector. The focal surface (slightly convex), uses the same Hamamatsu M64 PMTs already used in EUSO-Balloon, EUSO-SPB and Mini-EUSO. For the first time, the Cockroft HV power supplies and the ASICs used to digitize the anode signals will be positioned next to the anode pins, leading to a very flat camera. At the same time a new Zynq based digital data processing system, developed for the Mini-EUSO detector, will be used for the KLYPVE-EUSO photodetector module. These electronics are based on a new hardware solution using a system-on-chip concept. This allows to organize efficient data processing via a network structure of the photo detector with fast interfaces between modules and data storage. The new focal surface design and the photo detector module data processing system are presented and discussed.
