In the present work, a novel scheme for implementing the GM tube read-out functions is designed, in order to overcome the drawbacks of microprocessor-based designs. This scheme integrates the implementation of the signal processing, HV biasing, data processing and user interface functions onto a single-chip mixed-signal PSoC platform. Pulse count rates from GM tubes exposed to gamma photons are influenced by both exposure rate and gamma energy. This is because a GM tube's inherent detection effectiveness varies with gamma energy. Only an energy adjusted GM tube may be used in the current work on GM counter embedded readout. An energy compensated GM tube is coated with lead and/or tin. This metal coating is used to empirically match the efficiency vs energy curve of a particular tube. This empirical adjustment may be enhanced in situations when the gamma energies in the application of concern are known a priori. Once the survey meter sensitivity versus energy data is obtained, it may be used as a search up table in the firmware. Those correction factors may be incorporated in the firmware's engineering conversion codes. Battery monitoring and testing may be added. Composite dead layers in the unit cell may enhance neutron detector optimization calculations. In Monte Carlo simulations, sophisticated semiconductor detectors such as neutron converter coated avalanche photodiodes with statistically variable multiplication factors may replace basic PIN diode-based devices. The firmware for the alpha spectrometer may be enhanced with isotope identification, user controlled ramping rate, long term stability monitoring, and battery monitoring. More sophisticated reset switch control waveforms and ultra-low charge injection switches may be used to minimize residual errors in pulse height measurement and improve resolution. This study conduct research that has been accomplished in two important aspects of small radiation instruments, in particular, the execution of readout electronics using a novel reconfigurable mixed signal hardware platform, as well as the design and optimization of detectors.
