Description/Abstract:
THIS REPORT DESCRIBES THE PROCEDURE FOLLOWED AND THE RESULTS OBTAINED IN MEASURING, AS A FUNCTION OF TIME, THE PROMPT-GAMMA RADIATION EMITTE D WITHIN 1,000 MICRO SEC AFTER THE EXPLOSION OF THE ATOMIC WEAPONS STU DIED IN OPERATION GREENHOUSE. THE REPORT ALSO GIVES THE DESIGN OF THE EXPERIMENT AND A DESCRIPTION OF THE EQUIPMENT USED AND THE INSTALLATI ONS MADE. THE FAST COAXIAL SCINTILLATION DETECTORS DEVELOPED BY THE N AVAL RESEARC LABORATORY-HALL (NRLH) GROUP FOR THE GREENHOUSE TEST WERE USED WITHOUT COLLIMATORS AT A DISTANCE OF SEVERAL MEAN FREE PATHS FRO M THE SOURCE. NUMEROUS FACTORS COMPLICATED THE INTERPRETATION OF THE DATA OBTAINED, THUS REDUCING THE ACCURACY THAT MAY BE ASCRIBED TO THE RESULTS. THE PROBABLE PEAK GAMMA-RAY INTENSITY, THE TIME OF OCCURRENC E OF THE PEAK, AND THE PROMPT-GAMMA DECAY CURVES AS A FUNCTION OF TIME WERE OBTAINED FOR EACH SHOT. A COMPOSITE DECAY CURVE FITTING ALL THE SHOTS WAS OBTAINED, AND FROM THIS A SCALING FACTOR WAS DEDUCED WHICH RELATED THE SHOT ENERGY TO THE GAMMA-RAY INTENSITY.
