His for ede, December 1961: “N . tm > = ¢ { ° See - f / In the area of high altitude detection, the W-Division work which has been going on for many months has developed an open window photomultiplier detector which is to be placed aboard Discoverer missiles in October and December of 1962. These flights "should be useful in determining the radiation background which a $urverHance satellite a will encounter in space." The section on testing indicates that Fisher caused considerable equipment loss due to its yield and cratering effects. Three amplifiers and a power supply were completely destroyed and the zero rack and Perkins supply suffered lesser damages. Also, due to the high pressures experienced, the pressure transducer measurements on Fisher were of no value since the ranges chosen were too low. "The Bourdon pressure gauges yielded interesting informaiton although pressures developed were higher than gage ranges (greater than 300 PSI)." Thus far there has been no real mention of any possibilities for testing other than the NTS with the exception of the outfitting of the C-130 aircraft. Documentation in early December of 1961 indicates that Sandia is requesting 72M-5 Rocket Motors from the Army Guided Missle Agency (ARGMA) and is to fill the reaa uF quirement for diagnostic rockets See the 3 AEC Laboratories, PZ to be launched by Sandia, and requesting delivery by Feb 1, 1962. / Here are two letters from Harold Brown to Seaborg dated 1 Dec. on slightly differ ent subjj ects. beneeaienenetetentemmmeien Kh The firs i t covers the Proper procedures for inclusion of effects tests and Brown mentions i the " "confusi i on caused at our recent meeting (of the NSC sub-— committee) by the sudden injectio n of a high altitude effects shot sponsored LASL L." by With i this i somewhat misu i nderstood posii tion as a basis, Brown goes on to discuss the problems with the grey area in responsibility between the DOD and the AEC and the surface neut ron effects tests which has also come into the
