2. Test and Calibration of CUBES: a CubeSat X-ray Detector
University essay from KTH/FysikAbstract : CUBES is an X-ray detector that will be placed aboard the KTH 3U CubeSat mission, MIST. Its purpose is to detect high energy X-rays as well as to test various components in a space environment. Two CUBES will be placed on the satellite. Each CUBES consists of a printed circuit board (PCB) with three multi pixel photon counters (MPPCs). READ MORE

3. Digitised charged-particle discrimination in CsI detector signals
University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenAbstract : This work is aimed at improving the discrimination of protons and α particles in digitised signals from CsI(Tl) scintillators. This has been achieved using pulse-shape discrimination, wherein the shape of the pulses is used to learn which particle is detected. READ MORE

4. Software Development and Qualification Testing of a CubeSat X-ray Monitor
University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknikAbstract : The CUBES (CUbesat x-ray Background Explorer using Scintillators) is a payload on the KTH student satellite MIST (MIniature STudent satellite) to evaluate Silicon Photo-multiplier technology and new scintillators such as GAGG (Gadolinium Aluminium Gallium Garnet, Gd3Al2Ga3O12) for future use in hard X-ray polarisation studies of Gamma-Ray Bursts. CUBES itself is designed to study the MIST in-orbit radiation environment by using a detector which is comprised of a silicon photomultiplier coupled to different scintillator materials. READ MORE
