Abstract

A technique has been developed to prepare fission foils of uniform thickness on thin plastic films (VYNS-3) coated with Al, to be used as a cathode inside a 4π chamber. The optimum thickness of the Al-coating is 2.5 μg/cm² on both sides of the film. These films are brought in an ionisation chamber filled with a mixture of 98% A and 2% N₂. The influence of the thickness of the U²³⁵-film on the discrimination between fission and alpha pulses has been studied. The evaluated efficiency of the counter for a 1 mg/cm² U²³⁵O₂-foil is (92 ± 1)%; for a 0.1 mg/cm² foil (97.5 ± 0.3)%.
