SPACIROC: a Front-End Readout ASIC for the JEM-EUSO Observatory

Abstract : The SPACIROC ASIC is designed for the JEM-EUSO observatory onboard of the International Space Station (ISS). The main goal of JEM-EUSO is to observe Extensive Air Shower (EAS) produced in the atmosphere by the passage of the high energetic extraterrestrial particles above a few 10^19 eV. A low-power, rad-hard ASIC is proposed for reading out the 64-channel Multi-Anode Photomultipliers which are going to equip the detection surface of JEM-EUSO. Two main features of this ASIC are the photon counting mode for each input and the charge-to-time (Q-to-T) conversion for the multiplexed channels. In the photon counting mode, the 100% triggering efficiency is achieved for 50fC input charges. For the Q-to-T converter, the ASIC requires a minimum input of 2pC. In order to comply with the strict power budget available from the ISS, the ASIC is needed to dissipate less than 1mW/channel. The design of SPACIROC and the test results are presented in this paper. SPACIROC is a result of the collaboration between OMEGA/LAL-Orsay, France, RIKEN, ISAS/JAXA and Konan University, Japan on behalf of the JEM-EUSO consortium.
