Abstract

In this paper a vertec detector working as active target is described. It consists of a telescope of nuclear targets sorrounded by two coaxial cylindrical MWPCs, working in the proportional regime. The energy loss in the two 6 mm gaps of the chambers is measured with an accuracy better than 18%. The coordinates of the track along the sense wires are measured using the charge division method with an accuracy of 0.5-1.0%. The efficiency is about 99.5%. This device is used in an experiment concerned with multihadron production on nuclei, coupled with a forward spectrometer in order to detect and recognize grey, black and shower secondary particles.
