Abstract
Large diameter germanium crystals are needed to provide larger, more sensitive, gamma-ray detectors for nuclear physics measurements at DOE user facilities. In this project, germanium crystal growth techniques will be experimentally developed for the growth of large diameter crystals. Phase I will demonstrate the feasibility of a new growth technique. In Phase II, the technique will be completed to enable a new breed of commercially-available, very-large-diameter germanium gamma-ray planar detectors. Commercial Applications and other Benefits as described by the awardee: The technology should have immediate applications in research taking place at DOE user facilities involving nuclear physics, astrophysics, and rare-particle detection. Moreover, these detector systems should enable germanium detectors to enter commercially active fields, the most important of which is nuclear medicine.
