Abstract :
A pocket-size gamma-ray spectrometer has been developed. It uses a large volume (2 cm3) CdZnTe coplanar-grid detector to achieve good detection efficiency and energy resolution. The spectrometer is completely self-contained. It includes pulse processing electronics, multichannel analyzer, data storage, LCD display, keypads, USB interface, and rechargeable battery. Custom software was created for spectrum acquisition, storage, and display. The power consumption of the spectrometer is 120 mW when active, allowing two days of continuous operation on a full battery charge.
