DEVELOPMENT AND FABRICATION OF NON-DESTRUCTIVE SPECIFIC GRAVITY MEASURING EQUIPMENT EMPLOYING RADIATION TECHNIQUE

Abstract

A complete check-out of the density measurement portion of the system was initiated. The power control circuits were tested and found to operate satisfactorily with the exception of their behavior during power failures. The photomultiplier and its associated circuitry were checked and found to operate satisfactorily. The circuitry associated with the photomultiplier consists of a passive filter, a clipping amplifier and a tuned amplifier that processes the photomultiplier pulse signal so that it may drive the servo amplifier. The servo amplifiers were checked and found to operate properly. (Author)
