The environmental test campaign of GMOD: a novel gamma-ray detector

Abstract: The Gamma-Ray Module (GMOD) is a novel gamma-ray detector developed for the study of high energy astrophysical transients called Gamma-Ray Bursts. GMOD has been designed in-house and will be flown on board EIRSAT-1, intended to be Ireland's first satellite, a 2U CubeSat developed as part of the European Space Agency's Fly Your Satellite! programme. The detector comprises a 25×25×40mm CeBr 3 scintillator, coupled to a tiled array of 16 OnSemiconductor Silicon Photomultipliers with front-end readout provided by … Show more

“…Throughout the design and qualification stage of the life cycle, the spacecraft and payloads undergo numerous tests. Environmental testing may be conducted on the subsystem [4] and system level [8], which may also require pre-campaign functional and mission tests [9]. All of these tests can be used to inform additions or amendments to the existing functionality, providing feedback not found within the scope of the basic payload firmware requirements.…”

“…The Gamma-Ray Module (GMOD) is a <1U, gamma-ray detecting instrument which has been developed based on a heritage of tests (e.g. [4] and references therein). GMOD is the primary science payload on the 2U CubeSat EIRSAT-1 (Educational Irish Research Satellite) [5], a participant of the 2nd European Space Agency (ESA) Fly Your Satellite!…”

“…PTFE spacers support the detector components within the aluminium light-tight enclosure, forming the 75 mm × 51 mm × 42 mm detector assembly which is bolted to the motherboard. These spacers additionally provide good thermal isolation between the enclosure and the internal components, stabilising the scintillator and SiPM array temperature [50].…”

“…GMOD is a <1U scintillation based gamma-ray detecting instrument which features modern miniaturised detector technology in a robust and low power, CubeSat compatible form factor. The development of the GMOD detector builds on previous work including a number of technology investigations [6], [7], a five hour balloon flight at 37km float altitude [8], a 101.4MeV proton irradiation test [9] and most recently, the engineering qualification model environmental test campaign, including vibration and thermalvacuum testing [10]. GMOD is expected to detect ∼11-14 GRBs over a one year mission at a significance of 10 σ, within the standard 50 keV to 300 keV energy range [11].…”
