Product description
Louis. The BGO (Bismuth Germanium Oxide) shield will be incorporated into the payload of a stratospheric balloon flight experiment. The shield is made of three main components: (1) a 35.1 kg BGO crystal and a 6.9 kg BGO crystal, (2) an Al housing to hold the crystal and to keep it in a light tight environment, and (3) 8 Hamamatsu Photomultiplier Tubes (PMTs) with biasing electronics. The objective of the BGO shield is to detect X-rays that come from the X-ray mirror, which is part of the payload, through the opening in the BGO shield. The crystal scintillates when struck by energetic particles and the PMTs detect the scintillation light pulses. If an energetic particle hits the shield, it generates an anticoincidence signal which is read out by the PMTs.
CBP rationale
