. 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 - 67 - Se--+ =e =al
