Computerized gamma spectrometry at the Helsinki University of Technology

In this paper we describe our approach to designing a system for rapid and accurate processing of gamma spectra. Our measurements are done in a separate measuring station which consists of conventional equipment centered around a multichannel analyzer. The measured spectra are then transferred to a Nova 2 minicomputer based analysis station via a 70 m long cable at a 9600 baud rate with a special control program. Analyses can be perfomed with our new SAMPO80 code on the Nova or the data can be further transferred into the computer network of the University with another control program. Various aspects of the system design and development are discussed. (orig.)
