A LUMINESCENCE CHAMBER (in German)
A luminescent chamber, consisting of a homogeneous CsI-- Tl-scintillator and a four-stage magnetically focussed image intensifier was built. Using large aperture lenses for the imaging of the intensifier output screen to the photographic film, the light spot from a single photoelectron of the intensifier front-photocathode can easily be photographed. Intensification and resolution of the intensifier are about 10/sup 6/ and 0.1 mm respectively. The conditions for seeing tracks of minimum ionizing particles and the problems of spacial and time- resolution, of the depth of sharpness and the possibilities of stereo-viewing are discussed. Photographs of 400-Mev positron tracks are shown. The density of image spots in this case is 20 to 40 per cm track length. A comparison of the luminescent chamber with other track chambers is discussed. (auth)
