The measuring system described in this paper, developed for non-destructive neutron activation analysis, consists of a semiconductor
detector gamma-ray spectrometer and a sample changer coupled to a PDP-9 computer via a CAMAC interface system. CAMAC modules
implemented in this system are an ADC interface, a sample changer control, display unit, a timer and a time-of-the-year clock.
The spectra are accumulated in a section of the computer memory. The computer is further used for experiment control and for
the analysis and interpretation of the measured gamma-ray spectra.
