TL;DR: RHESSI as discussed by the authors is a Principal Investigator (PI) mission, where the PI is responsible for all aspects of the mission except the launch vehicle, and is designed to investigate particle acceleration and energy release in solar flares, through imaging and spectroscopy of hard X-ray/gamma-ray continua emitted by energetic electrons, and of gamma-ray lines produced by energetic ions.

TL;DR: RHESSI as mentioned in this paper uses a set of nine cryogenically cooled coaxial germanium detectors to resolve the line shape of every known solar gamma-ray line except the neutron capture line at 2.223 MeV.

TL;DR: In this article, the performance of high-purity Ge radiation detectors with amorphous Ge (a-Ge) contacts fabricated using RF sputtering techniques was investigated and shown to exhibit good blocking behavior with low leakage currents, with the contact biased under either voltage polarity.

TL;DR: The Transient Gamma-Ray Spectrometer aboard the Wind spacecraft in deep space has observed gamma-ray bursts and solar events for four years as discussed by the authors, and the germanium detector in the instrument has gradually deteriorated from exposure to the ≈10 8 p / cm 2 / yr (>100 MeV ) cosmic-ray flux.

TL;DR: In this article, a coded-aperture-based gamma-ray imager that uses a unique hybrid germanium detector system is described. But the performance of the planar detector, the hybrid system, and present images taken of laboratory sources are discussed.
