Abstract: Geiger-Mueller Counters filled with 3He have been the standard for detecting neutrons for many years, but the system is expensive, requires high voltage and has limited size scalability. Using solid state radiation detectors provides a significant improvement in cost, size, and performance. The widespread deployment of solid state neutron detector systems will require development of a low power and low cost amplifier. A previously described amplifier design was evaluated, but its high power consumption and BOM cost per diode area of $0.69/mm2 made it impractical for a portable and cost effective application. The proposed amplifier design is based on using off-the- shelf components and consumes less current, provides higher gain with higher signal-to-noise ratio, more tolerance to higher diode capacitance than previous amplifiers and a BOM cost per diode area of $0.026/ mm2.
