STATUS REPORT ON A LUMINESCENT CHAMBER

· Nucl. Instr. Methods
A magnetically focused 4-stage image intensifier was built for luminescent chamber experiments. Sandwich films consisting of phosphor screen, glass film, and photocathode surface were used. The image diameter of the tube is 3 cm. The light amplification is about 10/sup 6/. A homogeneous axial magnetic field of 1500 gauss was used, so that the electron helix-diameter defines the resolution independent of the applied voltage. The light spots produced by single photoelectrons have about 0.1 mm diameter. Tracks of cosmicray particles and 400-Mev positrons in CsI(Tl) were photographed with 1:1 imaging of the tracks on to the intensifier tube by means of two coupled f/l lenses. (A.G.W.)
