EERE . = PROGRAM 12 Project 12.1 = Threshold Detectors = Lee Aamodt - LASL Program 12 is concerned with neutron measurements and Project 12.1 in parte icular, with threshold measurements; but this shouldn't be confused with measure- ments of neutrons on an extensive scale. We are just making some neutron measure- ments on a fairly small scale for diagnostic purposes where we use the neutron measurements to tell us something aboutwhat is actuallygoingoninsidethe\— devices. | ' ( DELETED DELETER MELETEL ese me:surements will be fairly simple, just some cable wit 3 etectors on them and these detectors will be sent back probably on the day of recovery, which would be the day of the shot, for counting back here. An attempt will also be mide to count in the field, but this will probably be stopped sooner or later by fallout - so we will have to plan on counting then back here at LASL, The number of people involved will probably be two plus a couple of H&N people who will be borrowed out there to help in placing and recovering samples, Project 12.2 is a similar neutron measurement which is done by means of photo-= graphic plates in a 30-ton collimator using recoil protons and the purpose here is to get an accurate measurement of neutron spectrum for diagnostic purposes. The shots concerned are Erie and Blackfoot, with stations at 300, 450, 600, perhaps 750 yards on Erie and om Blackfoot, because yields are a little smaller, at 300, 450, and 600 yards. This will involve something like two first to June first, and two or three H&N thing we are going to need on these shots where most of the conflict has come in on or three people in the FA for fram April people to help with the recovery. One is a clear line of sight, and this is other operations,
