Yvonne, Eniwetok. The last two UCRL shots (Quince and Fig) were
fired on Yvonne. EG&G operated the diagnostic station. Complete alpha
versus time curves and high explosive transit time data were obtained.
The results of these experiments are contained in the preliminary shot
reports and in the various technical reports written by the groups involved.
Program 24, Phonex
Program 24 was conducted to measure the number and energy distri-~
bution of the neutrons leaving the surfaces of devices on the Maple and
Hickory events. The neutrons were detected by observing proton tracks left
in nuclear track emulsions by protons ejected from a thin polyethylene radi-
ator. The number of neutrons was determined from the density of proton
tracks in the emulsion coupled with the known geometry of the experiment.
The energies of the neutrons were determined from the ranges of the protons
in the emulsion. In order to protect the emulsions from blast and radiation,
the cameras were placed in heavily shielded collimators. For the Maple
event, three such collimators were placed on Fox at distances of 500, 760,
and 900 yd from the device. For the Hickory event two collimators were
placed on Tare at distances of 240 and 400 yd. The emulsions were successfully recovered from all stations and will be processed and scanned at Livermore..

TASK UNIT 4, SC PROGRAMS
Program 32, Doorknob
The original intent of Program 32 was to measure the neutron, x-ray,
total thermal, and gamma ray emission from a megaton range nuclear device
burst at an altitude of 250,000 ft. Additional measurements were incorporated
in the program as techniques became available for attempting them. These
were a sampling of the radioactive debris, optical coverage of the burst, and
a measurement of RF attenuation and refraction caused by the {ionization of
the atmosphere.
The techniques designed to accomplish the mission of the program and
the specific measurements and instrumentation tnvolved are.as follows:
1.
Stations for measuring the neutron, gamma ray, x-ray, and total
thermal emissions were put at specified locations by one- and two-stage
rocket-propelled instrument carriers. The propulsion units were modified
LaCrosse solid propellant motors. The auxiliary hardware was designed
specifically for these tests. The carriers were unguided, rail launched bal50
