TL;DR: The SuperCam body unit (BU) of the Mars 2020 rover as mentioned in this paper was designed to receive light from the mast unit via a 5.8 m opti-cal fiber and the light is split into three wavelength bands by a demultiplexer, and routed via fiber bundles to three optical spectrometers, two of which (UV and violet; 245-340 and 385-465 nm) are crossed Czerny-Turner reflection spectrometer, nearly identical to their counterparts on ChemCam.

TL;DR: In this paper, the authors used an 8 × 8 array of 6mm silicon photomultipliers (SiPMs) and an optimized amplification and summing circuit to achieve energy resolution of 5.5% at 662 keV and a figure of merit of 3.5, equivalent to the performance achieved with a 3-inch Hamamatsu R6233-100 PMT.

TL;DR: The Elpasolite Planetary Ice and Composition Spectrometer (EPICS) as discussed by the authors is an innovative and fully integrated NGRS with low resource requirements, which combines the gamma-ray and neutron spectrometers into a single instrument, leading to a significant reduction in instrument size, weight and power.

TL;DR: In this paper, the effects of high particle fluences on the dark current and the self-annealing time of silicon photomultipliers have been studied in the presence of high energy protons.

TL;DR: The Experiment for Space Radiation Analysis (ESRA) project as mentioned in this paper is the next in the series of Demonstration and Validation (DemVal) projects the Los Alamos National Laboratory (LANL) program will fly.
