The MAJORANA DEMONSTRATOR Readout Electronics System
N. Abgrall, M. Amman, I. J. Arnquist +76
The MAJORANA DEMONSTRATOR comprises two arrays of high-purity germanium detectors constructed to search for neutrinoless double-beta decay in 76-Ge and other physics beyond the Sta…
High Purity Germanium Based Radiation Detectors with Segmented Amorphous Semiconductor Electrical Contacts: Fabrication Procedures
Mark Amman
Radiation detectors constructed from large volume high purity Ge (HPGe) single crystals are widely used for gamma-ray spectroscopy. The detectors for this application can be simple…
Optimization of Amorphous Germanium Electrical Contacts and Surface Coatings on High Purity Germanium Radiation Detectors
Mark Amman
Semiconductor detector fabrication technologies developed decades ago are widely employed today to produce gamma-ray detectors from large volume, single crystals of high purity Ge…
Ultra-Low Noise Mechanically Cooled Germanium Detector
Paul Barton, Mark Amman, Ryan Martin +1
Low capacitance, large volume, high purity germanium (HPGe) radiation detectors have been successfully employed in low-background physics experiments. However, some physical proces…
Crystal growth and detector performance of large size high-purity Ge crystals
Guojian Wang, Mark Amman, Hao Mei +4
High-purity germanium crystals approximately 12 cm in diameter were grown in a hydrogen atmosphere using the Czochralski method. The dislocation density of the crystals was determi…
Characteristics of Signals Originating Near the Lithium-Diffused N+ Contact of High Purity Germanium P-Type Point Contact Detectors
The MAJORANA Collaboration, E. Aguayo, M. Amman +83
A study of signals originating near the lithium-diffused n+ contact of p-type point contact (PPC) high purity germanium detectors (HPGe) is presented. The transition region between…
