Abstract:This study presents a background estimation for the CubeSats Applied for MEasuring and LOcalising Transients (CAMELOT), which is a proposed fleet of nanosatellites for the all‐sky monitoring and timing‐based localization of gamma ray transients with precise localization capability at low Earth orbits. CAMELOT will allow us to observe and precisely localize short gamma ray bursts (GRBs) associated with kilonovae, long GRBs associated with core‐collapse massive stars, magnetar outbursts, terrestrial gamma ray flashes, and gamma ray counterparts to gravitational wave sources. A fleet of at least nine 3U CubeSats is proposed to be equipped with large and thin CsI(Tl) scintillators read out by multipixel photon counters (MPPC). A careful study of the radiation environment in space is necessary to optimize the detector casing, estimate the duty cycle due to the crossing of the South Atlantic Anomaly and polar regions, and minimize the effect of the radiation damage of MPPCs.

Abstract:The electric power supply of astronomical observatories has to manage a conflict of interest: Observatories are situated at remote locations, they have a high consumption of electric power while measuring electric signals as sensitively as possible. Within the project SLOBATCO, the question did arise, to what extent observatories have to rely on adequate power quality, for example, the perfectly sinusoidal shape of supply voltage and current, to ensure safe operation and accurate measurement results. International power quality standards are put in perspective with requirement specifications for observatories. This contribution describes the motivation, the underlying mechanisms that lead to issues, comments on the challenge in power systems engineering, proposes the instrumentation and installation, and interprets the first results. Experimental results clearly motivate the need for further measurement campaigns, as power‐quality‐related problems are common. A summary is provided together with an outlook and a motivation for future measurement campaigns.
