Abstract
LLNL¶V??FDPSDLJQ??IRU??GHYHORSLQJ advanced radiation detector materials has been accelerated over the last few years. We have pursued many different technologies including: scintillator crystals, ceramics, and polymers; thermal neutron detectors based on a boron-loaded silicon platform; organic high-energy neutron detectors; and the semiconductors TlBr and CZT with specialized contacts. In this paper, we discuss these technologies and future Safeguards needs.
