Scoville agreed that if one can predict within 10%, measurements were not necessary, but he did not think this is true yet. Blunda felt that if the RDB approved this and it does not interfere with diagnostic measurements, its inclusion should not be argued. He pointed out that we only have data_on_ one large-yield surface shot, and recalled the Buster blast measure- ments, | Tears flowed like wine. (Uy Cax proposed to go up to about 200 psi for these measurements, sincehe hadrno faith in the Ivy measuraments over 20 pai. BRL, SRI, and Sandia have \gl1 expressed interest in this work. One of the proposals for measur mM om the water shots is to measure the rate of travel of the shock along e-water photographically. (.11 agreed that this is a desirable methd¢}}clean and simple.) Also, BRL will prooftest at Inothole sare 60 self-re ording pressure-time gauges, which should take same of the strain off theinstrumentation.
