Phase 2 SBIR

Agency: Department of Energy
Topic: 42B-2014
Budget: 01/01/14 - 12/31/14

The Department of Energy maintains germanium gamma-ray detector arrays for Nuclear Physics research. Germanium gamma-ray detector technology has been an important factor in the historic success of these user facilities. The present and next generation facilities would be most effectively utilized by larger germanium detectors providing better sp...

Phase 1 SBIR

Agency: Department of Energy
Topic: 23A-2014
Budget: 01/01/14 - 12/31/14

The NNSA Defense Nuclear Nonproliferation missions include monitoring, assaying, and identifying Special Nuclear Materials (SNM). These activities commonly occur in facilities having large quantities of additional nuclear materials causing high background count rates that obscure measurements using ordinary spectroscopic radiation detectors. The...

Phase 1 SBIR

Agency: Department of Energy
Topic: 42 B-2013
Budget: 01/01/13 - 12/31/13

The Department of Energy (DOE) Office of Nuclear Physics maintains gamma-ray detector arrays as user facilities. The Modular Planar Germanium (MPGe) detector systems to be developed here will provide a lower cost, higher resolution, basis for such detector arrays. The MPGe detector systems will be experimentally developed by understanding the ra...

Phase 2 SBIR

Agency: Department of Energy
Topic: 45 C-2012
Budget: 01/01/12 - 12/31/12

DOE Nuclear Physics low-background rare-particle detection arrays require germanium detectors having the minimum possible background and maximum sensitivity. Larger p-type point-contact germanium detectors having better performance are being experimentally developed through collaboration with DOE low-background researchers. Semiconductor-detect...

Phase 2 SBIR

Agency: Department of Energy
Topic: 46 B-2011
Budget: 01/01/11 - 12/31/11

DOE Nuclear Physics user facilities require larger high-resolution gamma-ray detector systems to provide higher sensitivity measurements. Large diameter germanium crystals are being grown, evaluated, and iteratively improved in the laboratory. Large-diameter crystals will be made into large segmented planar detectors to demonstrate the viability...

Phase 1 SBIR

Agency: Department of Energy
Topic: 45 C-2011
Budget: 01/01/11 - 12/31/11

Difficulties associated with thick lithium-diffused entrance windows on the outside of p-type coaxial and point-contact germanium gamma-ray detectors have always been a technical hindrance. The lithium dead layer limits the low-energy detection range and adds background in the energy spectrum, thereby limiting commercial access to application ar...

Phase 1 SBIR

Agency: Department of Energy
Topic: 46 B-2010
Budget: 01/01/10 - 12/31/10

The existence of larger diameter germanium crystals will provide larger, more sensitive, gamma-ray detectors for Nuclear Physics measurements at DOE user facilities. Large Diameter germanium crystal growth techniques will be experimentally developed during the Phase I and Phase II. Large diameter germanium crystals will be grown and evaluated i...

Phase 2 SBIR

Agency: Department of Energy
Topic: 49 A-2010
Budget: 01/01/10 - 12/31/10

The semiconductor contacts on segmented germanium planar detectors require improvement to commercially supply better detectors at lower cost with faster delivery. In addition, this improvement will result in the utilization of significantly more high-purity germanium crystals for detector fabrication. The DOE operates user facilities for Nuclea...

Phase 1 SBIR

Agency: Department of Energy
Topic: 2009
Budget: 01/01/09 - 12/31/09

The semiconductor electrodes on segmented germanium planar detectors used in nuclear physics research require improvement, so that significantly more of the available high-purity germanium can be utilized for the detection function. This project will develop new semiconductor electrode technology for use in the fabrication of germanium detector...

Phase 2 SBIR

Agency: Department of Energy
Topic: 2009
Budget: 01/01/09 - 12/31/09

The next generation of DOE low-background user facilities will require suitable germanium crystal production capabilities. These crystal-growth techniques must accommodate the handling of highly enriched germanium in a manner consistent with low background counting. In this project, germanium crystal growth techniques will be experimentally de...
