N2 - This paper describes the design, construction, testing, and operation of hand-held thermal neutron detecting system (the 'B-10'). The neutron-sensitive element in the device is a Hamamatsu type 3590-04 silicon PIN photodiode coated with a thin (≈5 micrometer) coating of elemental 10B. Neutrons absorbed in the coating cause fissions from which one of the resulting charged-particles enter the diode where the particle's kinetic energy is converted into a charge pulse. Charge pulses are converted to voltage pulses and are counted by digital circuitry. The B-10 includes an on-board microcontroller, memory, RS-232 interface, and clock/calendar chip and can be set to operate in one of three modes: Integrating counter, multi-channel scaler, and single-event recorder. Data stored in the B-10 is available to the user through the RS-232 interface and software is provided to either display the data on a computer's screen or to write the data directly to a text file.
