Shuttle Flight Test of an Advanced Gamma-Ray Detection System

The Gamma-Ray Advanced Detector (GRAD) is a gamma-ray detector systems consisting of a large-volume, n-type germanium detector with active shielding of bismuth germanate and plastic scintillators. It was diverted from the AFP-675 program to a balloon flight over Antarctica following the Challenger D...

Description
Summary:The Gamma-Ray Advanced Detector (GRAD) is a gamma-ray detector systems consisting of a large-volume, n-type germanium detector with active shielding of bismuth germanate and plastic scintillators. It was diverted from the AFP-675 program to a balloon flight over Antarctica following the Challenger Disaster and the discovery the following year of the supernova 1987A. The present report outlines activities leading to and following the decision to go to Antarctica and summarizes the basic technological results from the project. Keywords: Gamma ray detector, n type Germanium detector.
