Navy representatives attended the meeting, and a progr agency coordination was worked out. RCA was given instructionb to pro- ceed with the development of two types of photomultiplier tub both of which will provide. research tools for the AEC scientists, faciBitating certain physical measurements which have been either very diff—icuit or actually impossible.

A proposal for the Radiation Instruments Branch's participation in Project Greenhouse has been submitted to Los Alamos. The primary object of this participation will be the field evaluation of ci ian defense type instruments being developed umder AEC sponsorship. A series of spectral dependency measurements has been made in cooperatfion with the Bureau of Standards to obtain information required for Projeck Greenhouse. OOEIARCHIVES |
