Compact neutron detectors are being designed and tested for use as low-power real-time personnel dosimeters. The neutron detectors are pin diodes that are mass produced from high-purity Si wafers. Each detector has thousands of circular perforations etched vertically into the device. The perforations are backfilled with LiF to make the pin diodes sensitive(More)
Excessive leakage current in perforated pin diodes was identified and addressed through simple changes in processing techniques. The first pulse height spectra from a perforated diode operated as a radiation detector is reported. Also, methods to load <sup>6</sup>LiF neutron absorbing material into deep perforations are reported.

The technology base formed by the development of high peak power simulators, laser drivers, FEL's, and ICF drivers from the early 60's through the late 80's is being extended to high average power short-pulse machines with the capabilities of supporting new types of manufacturing processes and performing new roles in environmental cleanup applications.
