PROGRAM 15

Project 15.1 - EG& Photography (Cloud, Fireball and Bhangmeters) Herb Grier - EG&G
22.2 - Remote Alpha Measurements
23.1 - Ball of Fire & Bhangmeter
23.2 = Cloud Photography

Our problems are two-fold; first, we're a service organization in that we do

the timing and firing for the entire technical group, and second, we're experimenters in that we measure alpha on some of the shots, measure yield photographically,
and do a lot of assorted tasks, which I think are of no real interest to a group
this big.
I'd like to run over the odd tasks a little bit and then spread the good word
on the timing system. The alpha task, I believe, will be covered later by John

Malik so it suffices to say that we're measuring alpha on Cherokee at Namu.

The

station is not yet built and we don't know how to build it, but we have faith in
Brother Campbell here. We're also measuring alpha on the Runit shots. There's a
little side experimertation that goes along with that - not too complicated.
The photographic effort has always been a big one - it is one of the yield
measurements and the yield is one of the characterisitics people want to know
about. We're operating essentially three photo towers in Bikini and a station
atop Gaelen Felt's bunker up on Aomoen. On Eniwetok, we're operating a photo
tower on Piiraai, one on the coral head, and then a couple of these small bunker
stations atop other installations.

We're delinquent as usual on getting construc-

tion things in, but these are pretty well set now and I think everybody is reasonably
happy.
The part of our work that I think will interest most people is the timing and
firing system. While we do the work, we're not the people you come and beat on.
In your status report, you should notify, through the distribution, Campbell if
you want signals here and there and everywhere else, what they are, whether they
be radio or wire. A new requirement, which I think we're got to get to avoid
confusion, is where do you want a voice countdown and on what frequencies? Is
the requirement in airplanes, or should we notify the rabbits. Things like this
have got to be written down.
Now the timing system is going to be very much similar to the CASTLE system.
Enivetok is no great problem. There are wires all over the lot, but in Bikini the
cable is limited and for people who want to get stations where there is no existing
cable, we will supply radio signals.
Within the next two weeks, we will get out copies which are essentially a
rewrite of the CASTLE timing manual. This specifies eix common wire signals and
radio signals. This has been found to be pretty much the kind of thing that is
