Abstract
The development of a portable multichannel analyzer for gamma spectroscopy applications is described. The developed unit is based on the Intel 8751 single chip microcontroller and has CRT and liquid crystal displays, preamplifying and amplifying sections, high voltage supply, built-in printer and runs on rechargeable batteries. The design uses standard off the shelf components, minimizes chip count by using all the microcontroller's resources and implementing most functions in software, and this results in a low cost system with good performance. Hardware and software design along with their integration are discussed.
