Interface formation and Schottky barrier height for Y, Nb, Au, and Pt on Ge as determined by hard x-ray photoelectron spectroscopy

AIP Advances, 2023
Development of a robust, thin, hole-blocking (n+) contact on high purity germanium (HPGe) has been the main challenge in the development of Ge-based radiation sensors.

Gamma-ray tracking with segmented HPGe detectors [PDF]

Brazilian Journal of Physics, 2003
This paper gives a brief overview of the technical progress that can be achieved with the newly available segmented HPGe detectors. Gamma-ray tracking detectors are a new generation of HPGe detectors which are currently being developed to improve significantly the efficiency and resolving power of the 4 … germanium detectors arrays for high-precision ∞-

Design study of a HPGe detector array for β-decay investigation in laboratory ECR plasmas

Frontiers of Physics, 2022
In the frame of the PANDORA project, a new experimental approach aims at measuring in-plasma β-decay rate as a function of thermodynamical conditions of the environment, namely a laboratory magnetized plasma able to mimic some stellar-like conditions ...

Production and Decay of the Ge73-m Metastable State in a Low-Background Germanium Detector [PDF]

, 2008
The $\ge73m$ metastable states decay with a very characteristic signature which allow them to be tagged event-by-event. Studies were performed using data taken with a high-purity germanium detector in a low-background laboratory near a nuclear power ...

Operation of a high purity germanium crystal in liquid argon as a Compton suppressed radiation spectrometer [PDF]

, 2006
A high purity germanium crystal was operated in liquid argon as a Compton suppressed radiation spectrometer. Spectroscopic quality resolution of less than 1% of the full-width half maximum of full energy deposition peaks was demonstrated.

New method for the production of thin and stable, segmented n$$+$$ contacts in HPGe detectors

European Physical Journal A, 2021
The realization of pulsed-laser diffused, thin n$$+$$ + contacts on high purity germanium (HPGe) and their successful segmentation is described. The contacts have been obtained by a laser-induced diffusion of Sb atoms, deposited by sputtering on Ge ...

Alpha Backgrounds for HPGe Detectors in Neutrinoless Double-Beta Decay Experiments [PDF]

, 2011
The Majorana Experiment will use arrays of enriched HPGe detectors to search for the neutrinoless double-beta decay of 76Ge. Such a decay, if found, would show lepton-number violation and confirm the Majorana nature of the neutrino.

Estimation of Fano factor for oversquare HPGe detector

Radiation Protection and Environment, 2022
Fano factor is a quantity used to measure the departure of the observed variance in the number of charge carriers produced from that predicted using poison statistics. Fano factor varies with the detector type.
