There were really three classes of experiments scheduled. No delay of the implosion test on the first practicable date could be supported on the basis, “Our experiment is so important that the test must be delayed until we are ready.” Some overlap was allowed for the simpler experiments. Hirschfelder on fallout expectations.Įvery new suggestion of a useful measurement was considered on the basis of value, time scale for completion, and available personnel and shop time. Penny advised on blast problems and Joseph 0.

Later in 1944 Enrico Fermi joined for nuclear experiments, and in the spring of 1945, William G. He supplied and updated the predictions of the expected yield of the implosion bomb and its radioactive, optical, physical, and nuclear effects-properties essential to planning all of the measurements. Weisskopf was the chief consultant on plans for instrumentation of the test. We had asked Groves to keep his VIP list below 10 in number. But on June 1, 1945, in addition to military camp personnel there were 210 scientists and technical aides, 250 by the middle of July, and a total of 425 on the weekend of the test, and a few special guests. In the autumn of 1944, the plan for a camp completed in December called for housing 160 military and civilian personnel. Army Engineers did not have the special equipment needed for some construction work, contracts had to be let to civilian firms in order to meet the increasingly tight schedule. Bush and many others at Trinity whom they had known at Los Alamos. But trailer-housed itinerant workers, indigenous to that part of the country, recognized Lt. It was Security’s hope that the Trinity site would not be associated with Los Alamos, 230 miles away. Slithering on the soapy adobe road we passed through the barracks area and returned to Socorro without being challenged. At that lower elevation the snow had become rain.

We returned to the valley where I had my car. The snow flakes got bigger, the snow got deeper, and with increasing altitude, the trees got closer together and finally blocked our passage. A sergeant brought a Weasel by truck from Los Alamos and met us at the north end of the Sierra Oscura. My first view of the Trinity base camp was in January with David Anderson when we sought a location for an SCR-584 radar to try to follow the ball of fire if the test were successful.
