Popis: In order to eliminate drifts encountered in electromechanical Mossbauer spectrometers, a drive has been developed which is drift free with regard to velocity as well as position. The spectrometer can be driven in two modes: constant acceleration and constant velocity. The constant acceleration input signal is the analog output of the address scalers of a multichannel analyzer running as a multiscaler (time mode). The constant velocity is obtained from a photocell slit system which drives the input of the spectrometer with a rectangular wave. In both modes, the photocell system is used to eliminate all position drifts by starting each new cycle from the same position. To analyze the velocity of the spectrometer a voltage‐to‐frequency converter and multichannel analyzer are used.
