“…For this reason, several proposals to NASA and ESA have been already submitted to select the successors of these instruments. Some notable proposals include: THESEUS [238], SVOM [28], e-ASTROGAM [85], AMEGO-X [52] and several CubeSats missions [40,97] (BlackCAT [92], BurstCUBE [201], COMCUBE [154], COMPOL [271], CUSP [91], EIRSAT-1 [185], GRID [265], GRBAlpha [194], GTM [56], IGOSat [204], IMPRESS [230], LECX [45], LIGHT-1 [13], MAMBO [39], MeVCube [163], Min-XSS1 [169], Min-XSS2 [170], SOCRATES [77], VZLUSAT-2 [216]).…”

The SpacePix2 monolithic active pixel sensor (MAPS) is a novel ASIC for space radiation monitoring designed in a 180 nm SOI CMOS technology. The active sensor area is 3.84 × 3.84 mm2, pixel matrix is arranged as a 64 × 64 array with 60 µm pitch. The pixel front-end amplifier signal range is 2–80 ke−, extended up to 30 Me− using a backside channel. Diodes integrated in the handle wafer in each pixel are biased at −150 V. Impinging particle generates a charge pulse converted to voltage pulse by charge sensitive amplifier (CSA). Maximum voltage memorized by the peak detector hold (PDH) circuit is digitized using on-chip 10-bit asynchronous column SAR ADCs. Two readout interfaces are available, 400 MHz LVDS and 50 MHz SPI. Total power consumption is 43 mA from a 1.8 V power supply. The ASIC has been tested in space in low Earth orbit (LEO) and sample data are shown.
