The first civilian defense type instrument which has become available
under the Sranch's development program has been tested at the Bureau
of Standards for energzy dependency and by the Signal Corps at Fort
Lionmouth, New Jersey for rugsedness and temperature and humidity de-
pendency. Freliminary data indicate that the instrument is quite
satisfactory, fron doth the radiation energy and ruggedness considerations. A procedure has been established whereby other instruments,
as they become available, will be ziven the same tests.
The Steering Committee of the Atomic BNergy Commission's Special Lube
Develooment“Program met in Princeton, New Jersey for the purpose of
formulating a vorogran of research and development to be conducted at
the research laboratories of the Radio Corporation of America under
AEC contract, Navy representatives attended the meeting and a pro-
gram of inter-agency coordination was worked oute
2°A was ziven
instructions to proceed with the development of two tyves of photo-
multiplier tubes, both of which will provide research tools for the
AEC scientists, facilitating certain physical measurements which have
been either very difficult or actually impossible. Preliminary investigations will also be started on a combination electron gun
photomultiplier device for use in the analysis of radiation spectra,
& series of meetings was held between representatives of the Naval
Research Laboratory and Atomic Enerzy Commission personnel to exchange
information on halogen filled Geiger counters and on techniques for
measuring charecteristics of scirtillators for use in scintillation
counters.
A proposal for the Kadiation Instruments Branch's participation in
Project Greenhouse has been submitted to Los #lamos.
The primary
object of this participation will be the field evaluation of civilian
defense type instruments being developed under AEC sponsorship.
A
series of spectral dependency measurements have been made in cooperation with the Bureau of vtandards to obtain information required
for Project Greenhouse.
