PHOTOePHYSICS
Objectives:
1.
To obtain radius time deta for hydrodynamic yield determinotions.
2.
To determine the nature end behavior of a nuclear detonation
by photographing the light produced during the initial stages of
the detonation,
3.
To study the reaction rate in the secondary of a megaton two
stage device by means of gammis and neutrons emitted from the suc-
ondary et various positions.
Techniques:
1. Framing cameras were operated from several photo stations on
each snot to record the growth of the firebell.
2. Very high speed streak cameras were used to record the history
of the light arising near the bomb in the first few microseconds,
3 A pinhole in a mile long vacuumpipe was used to collimate. gamma
rays and neutrons onto a plistic fluor. Lizht from the fluor was
photogrephed with high speed streak cemeras to record the gemma
time history and the arrivel rate of the neutrons. The latter makes
possible the determination of the neutron spectrum at various places,
Results:
1. Results of this prosram are civen in the individual project
