A versatile multiple Mossbauer spectrometer

Abstract

A Mossbauer spectrometer system, based on a PDP 11/10 minicomputer and capable of accumulating up to eight simultaneous spectra, has been designed and constructed. The system allows the data in each spectrum to be handled without interference to the other accumulating spectra. The computer is used to generate the velocity reference signal, removing the need for a separate waveform generator, and enabling a very smooth waveform to be calculated and used.
