THERMOLUMINESCENT DOSIMETER COMPUTOR-INDICATOR SYSTEM.
EDGERTON GERMESHAUSEN AND GRIER INC SANTA BARBARA CALIF
Five computer-indicators and 500 detectors based on the Phase II experimental models have been produced. Official designations given to these units by BuShips are Computer Indicator, Radiac CP784 XN-1 PD and Detector, Radiac DT284 XN-1 PD. The production of the detectors involved the preparation of the thermoluminescent phosphor, the manufacture of the vacuum tube detectors, the digitally coded handles, locks, plastic tube bases and spacers, and the detector cases. A special plastic had to be selected for the tube bases and spacers when it was found that the standard type was unsatisfactory. The computer-indicators incorporated a new photomultiplier tube that increased the sensitivity over that obtained in the experimental model. Complete manufacturing drawings were made to produce the computer-indicator and detectors. Production tests on the detectors and computerindicators indicate that the performance specifications of the contract have been met. Author
