Description/Abstract:
THE RESULTS FROM LABORATORY TESTS AND TEST FIRING WERE QUITE ENCOURAGI NG. IT WAS CONCLUDED THAT (1) THE BETA DENSITOMETER IS A FEASIBLE DEV ICE FOR THE MEASUREMENT OF DENSITY AS A FUNCTION OF TIME IN THE SHOCK WAVE FROM A NUCLEAR EXPLOSION. IT IS LIMITED TO PRESSURE LEVELS OF 6 OR 8 PSI FOR BOMBS IN THE RANGE OF 50 KILOTONS BUT IS CAPABLE OF HIGHE R PRESSURE LEVELS ON LARGER BOMBS WHERE THE INTERFERENCE FROM GAMMA RA YS IS LESS SERIOUS; (2) DUST-LOADING BEHIND THE SHOCK WAVE IS A MAJOR PERTURBATION TO THE IDEAL HYDRODYNAMICS AND CAN CHANGE THE DENSITY BY AS LARGE A FACTOR AS THE SHOCK ITSELF; (3) THE RISE TIME AT DISTANCES OF 7.5000 FEET ON EASY SHOT WAS SHARP WITHIN A RESOLUTION OF APPROXIMA TELY 0.2 MSEC; AND (4) THE FIELD CALIBRATION USED ON OPERATION GREENHO USE APPEARED REASONABLY ACCURATE AND WAS WORTHY OF SUBSEQUENT DEVELOPM ENT.
