Sputtered yttrium metal forms a thin hole-barrier contact on both p- and n-type germanium semiconductor detectors. Yttrium contacts can provide a sufficiently high hole barrier to prevent measurable contact leakage current below ∼120 K. Detectors h

A search for spectral lines in gamma-ray bursts detected with the Transient Gamma-Ray Spectrometer has been unable to confirm their existence. The spectrometer, aboard the Wind spacecraft, has detected gamma-ray bursts and other transients since 1995

A reverse-electrode closed-end germanium coaxial detector was irradiated with 183-MeV neutrons to evaluate the value of Pulse Shape Discrimination (PSD) techniques in restoring the energy resolution and line shape of the radiation damaged detector. T

The Transient Gamma-Ray Spectrometer aboard the Wind spacecraft in deep space has observed gamma-ray bursts and solar events for four years. The germanium detector in the instrument has gradually deteriorated from exposure to the ≈10 8 p / cm 2 / y

Pusle-shape discrimination (PSD) techniques on current pulses from coaxial germanium detectors can significantly correct for charge losses due to hole trapping caused by radiation damage. Numerical simulations of PSD indicate that by measuring the tw
