Radiation damage of J-series silicon photomultipliers (SiPMs) has been studied in the context using these photodetectors future space-borne scintillation detectors. Several SiPM samples were exposed to 101.4 MeV protons, with 1 neutron equivalent fluence ranging from 1.27×108 neq/cm2 1.23×1010 neq/cm2. After irradiation, SiPMs experienced a large increase dark current and noise, which may pose problems for long-running space missions terms power consumption, thermal control detection...
The Educational Irish Research Satellite (EIRSAT-1) is a 2U CubeSat developed at University College Dublin. project aims to build, test, launch, and operate Ireland’s first satellite perform in-orbit demonstrations of three novel payloads in-house. To reduce risk within the mission, employs prototype model philosophy in which two models spacecraft exist: an engineering qualification (EQM) flight (FM). This paper presents verification approach functional tests implemented for EIRSAT-1...
CubeSats facilitate rapid development and deployment of missions for educational, technology demonstration, scientific purposes. However, they are subject to a high failure rate, with leading cause being the lack system-level verification. The Educational Irish Research Satellite (EIRSAT-1) is CubeSat mission under in European Space Agency’s (ESA) Fly Your Satellite! Programme. EIRSAT-1 2U three novel payloads bespoke antenna module, which all contribute complexity project. To increase...
Scintillators synthesised as glass-ceramics have several potential benefits compared to the currently-used halide scintillators, including non-hygroscopicity, mechanical ruggedness, ease of producing customisable shapes, and for low-cost synthesis. The use these scintillators is considered a gamma-ray telescope operating in 0.2MeV-50MeV photon range. Inorganic scintillator compounds suitable incorporation into are assessed. In addition, families glass hosts scintillating also reviewed.
CubeSats are a small satellite technology that first emerged in the space sector early 2000s. Their low-cost, fast-delivery design has made more accessible, leading to significant increase number of satellites launched per year as well nations launching satellites. As an example, Educational Irish Research Satellite, EIRSAT-1, is CubeSat being developed by student-led team at University College Dublin, aiming launch Ireland's satellite. Originally viewed educational tools, capabilities...
The Gamma-Ray Module (GMOD) is a novel gamma-ray detector developed for the study of high energy astrophysical transients called Bursts.GMOD has been designed in-house and will be flown on board EIRSAT-1, intended to Ireland's first satellite, 2U CubeSat as part European Space Agency's Fly Your Satellite!programme.The comprises 25×25×40mm CeBr 3 scintillator, coupled tiled array 16 OnSemiconductor Silicon Photomultipliers with front-end readout provided by IDE3380 SIPHRA.The received GMOD...
The Gamma-ray Module (GMOD) is an experiment designed for the detection of gamma-ray bursts in low Earth orbit as principal scientific payload on a 2-U CubeSat, EIRSAT-1. GMOD comprises cerium bromide scintillator coupled to silicon photomultipliers which are processed and digitised by bespoke ASIC. Custom firmware motherboard has been designed, implemented tested MSP430 microprocessor manages including readout, storage configuration system. verified series experiments testing response over...
