Abstract

A. first generation 120 micron pitch pixel array system for neutron detection using the PATARA amplifier chip was assembled and tested. The pixel array was tested for neutron response and spatial resolution. Pulses from the PATARA were observed at 0.5 V in height and 500 ns wide from neutron interactions. The spatial resolution of the array was determined to be 119 micrometers. Leakage current tests and alpha particle irradiation tests were conducted for a second generation prototype silicon sensor with 175 micrometer deep perforated trench structures in each pixel. The second generation sensor incorporates several design improvements to ease fabrication.
