Radiation tolerance tests on particle detector components such as SiPMs and their associated electronics are crucial to the success of high-energy physics experiments and scientific missions in space. To this end, an 18 MeV proton beamline is operational at the medical cyclotron of the Bern University Hospital (Inselspital). While the cyclotron’s primary purpose is the production of medical...

ChipIr is a beamline dedicated to the irradiation of microelectronics with atmospheric-like neutrons; it has been built on the second target station of the ISIS spallation source at the Rutherford Appleton Laboratory, UK. The beamline is specifically dedicated to the study of single event effects and its design is therefore optimized to extract a neutron spectrum as similar as possible to the...

Most of the astrophysics experiments use astro particle detectors comprising scintillators coupled large number of photomultipliers (either PMTs or SiPMs) to generate the electrical pulses corresponding to the detected particle. The performance of the detectors is strongly dependent to the parameters of each photodetector and therefore they have to be thoroughly and individually characterized...

Radiation damage of J-series SiPMs has been studied in the context of using these photodetectors in future space-borne scintillation detectors. Several SiPM samples were exposed to 101.4 MeV protons, with fluences ranging from 1.0e8 p/cm$^2$ (1 MeV neutron equivalent fluence of 1.3e8 neq/cm$^2$, absorbed dose of 9.8 rad) to 9.3e9 p/cm$^2$ (1.2e10 neq/cm$^2$, 908 rad). An increase in the dark...

We studied 200 MeV proton irradiation effects on Hamamatsu MPPCs (Si-PMs) in the Wakasa-wan Energy Research Center in Japan. Hamamatsu K.K. made test versions of MPPCs (S14420-3050MOD, S14160-3050MOD) and we studied these performances. As a result, dark current and lower energy threshold of modified MPPCs were comparable to the old one, and thus there were no significant improvements observed...

Silicon Photomultipliers (SiPMs) are quickly replacing traditional photomultiplier tubes (PMTs) as the readout of choice for gamma-ray scintillation detectors in space. While they offer substantial size, weight and power saving, they have been shown to be susceptible to radiation damage. SiPM models from various manufacturers were irradiated with 64 MeV protons to simulate the radiation...

POLAR-2 is a polarimeter built to investigate the polarization of gamma-ray bursts in a cosmic space. The instrument will be launch in 2024 on board of the China Space Station and is therefore subject to background radiation from cosmic rays and solar flares. Contrary to its predecessor POLAR, where the scintillators were read-out using a multi-anode PMT, the plastic scintillators will be...

We studied annealing characteristic of Hamamatsu MPPCs (Si-PMs) in two ways after 200 MeV proton irradiation. First, we report the annealing characteristic after kept in room temperature during seven months. Second is baking at 150 degrees Celsius during 3 hours. In both cases, the increased dark current is reduced by 1/2-1/3.

The last decade has increasingly seen the use of silicon photomultipliers instead of photodetectors like photomultiplier tubes. This is due to various advantages of the former on the latter like the compactness, lower operating voltage, insensitivity to magnetic fields and mechanical robustness. All these features make silicon photomultipliers ideal for use on space based experiments where the...

SiPMs performance parameters such as dark count rate, the average number of detected photons, cross-talk and after-pulsing, gain and gain fluctuations, are usually extracted from
the pulse-height spectra obtained in the dark or response to low-intensity light illumination.
This method works for non-irradiated SiPMs. The most critical effect of radiation on SiPMs is the increase...

Mu3e is a novel experiment under preparation at PSI searching for lepton flavor violation in the neutrinoless $\mu \rightarrow eee$ decay. To suppress accidental backgrounds a scintillating fiber timing detector read out with multi-channel SiPM arrays at both ends has been developed.

We measured 200 MeV proton damages on Hamamatsu MPPCs (Si-PMs), S13360-6050CS and S14160-6050HS, using the Wakasa Wan Energy Resarch Center in Japan. To achieve the lower energy threshold of CsI(Tl) with the damaged MPPCs, we measured the performances at different operation voltages and temperatures. The lower operational voltage is preferred due to the large increase of the dark current. The...

Each GECAM satellite is equiped with 25 SiPM-based gamma-ray detectors (GRD) and 8 SiPM-based charged particle detectors (CPD).

The main effect of radiation damage in a Silicon-Photolumtiplier (SiPM) is a dramatic increase in the dark current. The power dissipated, if not properly cooled, heats the SiPM, whose performance parameters depend on temperature. Heating studies were performed with a KETEK SiPM, glued on an alumina substrate, which is either directly connected to a temperature-controlled chuck of a probe...

Silicon photomultiplier (SiPM) has recently been used in several space-borne missions for scintillator readout, thanks to its solid state, compact size, low operating voltage and insensitivity to magnetic fields. However, a known issue of operating SiPM in space environment is the radiation damage and thus the performance degradation. In-orbit quantitative study of these effects is still very...

Due to the plethora of SiPM types, instrument configurations and their respective orbital operations it is sometimes very difficult to easily characterize the origin of “SiPM radiation damage features”. Even more so, it can be difficult to translate the results from another group/collaboration into something useful for yourself.

The Gamma-ray Burst Localizing Instrument (GALI) is a new concept for localizing γ-ray bursts (GRBs), by utilizing the mutual occultation between numerous small scintillators. In a sense, the method is similar to the coded mask aperture, only that the mask itself is composed of detecting scintillators, so that most of the photons are being detected. The large number of scintillators...

The Cosmic X-ray Background (CXB) dominate the X-ray fluxes over the sky, as it is believed to be a superposition of numerous discrete sources, which are primarily Active Galactic Nuclei (AGNs). The CXB intensity therefore offers an unique probe to study the AGN population. Limited by background modeling and (cross) calibration issues, the uncertainty of the CXB measurements remain currently...

Neutrons and γ-rays are produced throughout the heliosphere and offer a unique window to understanding the fundamental processes of energetic particles. At the Sun, because neutrons and γ rays are produced by the interaction of accelerated ions in solar eruptive events, they can further our understanding of space-weather agents, processes and effects.
