Long-term performance of SiPMs in space environment measured by GRBAlpha, GRBBeta, and VZLUSAT-2 CubeSats
Jakub Ripa, Filip Munz, Marianna Dafcikova +46
In this work, we report the successful application of silicon photomultipliers (SiPMs) in gamma-ray burst (GRB) detectors used in CubeSats operating in the low Earth orbit (LEO) ra…
Characterization of more than three years of in-orbit radiation damage of SiPMs on GRBAlpha and VZLUSAT-2 CubeSats
Jakub Ripa, Marianna Dafcikova, Pavel Kosik +42
Silicon photomultipliers (SiPMs) are prone to radiation damage which causes an increase of dark count rate. This leads to an increase in low-energy threshold in a gamma-ray detecto…
Early results from GRBAlpha and VZLUSAT-2
Jakub Ripa, Andras Pal, Masanori Ohno +37
We present the detector performance and early science results from GRBAlpha, a 1U CubeSat mission, which is a technological pathfinder to a future constellation of nanosatellites m…
GRBAlpha: A 1U CubeSat mission for validating timing-based gamma-ray burst localization
András Pál, Masanori Ohno, László Mészáros +26
GRBAlpha is a 1U CubeSat mission with an expected launch date in the first half of 2021. It carries a 75 x 75 x 5 mm CsI(Tl) scintillator, read out by a dual-channel multi-pixel ph…
