PHOTOGRAPHY OF COSMIC RAY TRACKS WITH A CASCADE LUMINESCENT CHAMBER. Report No. 2900-11-T

Technical Report ·
OSTI ID:4194404
A cascade luminescent chamber made up of three image tubes coupled with refractive optics was used to photograph tracks of cosmic ray mu mesons in a sodium iodide crystal. The very high time resolution and postevent triggering achieved through these experiments will facilitate experimentation with impure beams from acceleration and with cosmic rays. The apparatus is described with details of measurement on image tube characteristics and the nature of background. The same type of apparatus is applicable to other problems where very weak light signals (several thousand photons total) must be photographed. (auth)
