Abstract

SPRITE, the first NASA-funded 12U CubeSat for astrophysics science, will use an ultraviolet light spectrograph with a photon-counting microchannel plate detector to provide spatial and spectral data on the light observed from low-redshift galaxies, active galactic nuclei, and shocked emission features of supernova remnants in the 1000Å − 1750Å bandpass. This proceedings describes recent progress on the design, implementation, and experimental evaluation of SPRITE’s electrical subsystems, particularly the high voltage power supply required to drive the microchannel plate detector. Measured experimental results for the commercial high voltage power supply module and the electronics board designed and built to control it are presented and discussed. The average voltage and voltage ripple of the high voltage power supply output when driving a resistive load that simulates the load anticipated on orbit due to the detector and a parallel voltage divider are presented. Planned revisions to the SPRITE electronics design are discussed, including modifications to be made to the high voltage power supply control board and the addition of an electronics board to handle all the interfaces between the command and data handling subsystem and the instrument electrical subsystems. SPRITE is planned to launch in early 2023 and will provide on-orbit data for the microchannel plate detector and other technologies onboard that are candidates for use on future large missions.
