Pome ~1]~ Further program discussions address the Plowshare program to which a great deal of space is given, and the program for detection of underground nuclear explosions which includes planning and work underway for the Lollipop test in granite. Also details of the Cowboy program underway are presented. reveiw The mid-year from Brown to Shute on 15 July 60 contains several significant items. "A new area (Area 410) is being set up at NYS for the purpose of conducting hydrodynamic experiments which cannot be carried out at site 300.. This area should be operating in Sept. or Oct. of 1960." In the area of Vela, there are several interesting points made. Uniform, As for Vela “Livermore plans to take no primary responsibility except for the Lollipop in granite, which may take place later in Sept. 60, and the decoupling shots which can be carried out sometime in 1961 depending on the size of the salt cavities which may eventually be decided upon. For these experiments LRL plans to take responsibility for staging shots and for coordinating close-in measurements only, immediate and distant measurements being the responsibility of others, For other shots LRL will serve only in an advisory capacity, concerning ourselves principally with the theory of coupling of energy from the explosion into the seismic waves. ARPA has overall supervision of the program. If no adequate program of nuclear explosions for measurement of decoupling is authorized, it will be desirable to carry out further chemical explosions at Winnfield with gaseous explosives."" In the area of Vela Hotel, Livermore has received some money from ARPA to carry out studies on background radiation in space during FY 60. Together with lab programs for neutron albedo from the earth's atmosphere and neutron emulsion work in the Van Allen radiation belt, to be carried out in FY 61 and 62, these 3 programs have been proposed as a package to ARPA for possible
