Sumario:At the CERN SPS (Super-Proton-Synchrotron) most of the secondary beams are provided with a momentum measuring section. Each spectrometer consists of four multiwire proportional chambers with a fast readout system allowing a multi-user access. The chambers are operated with an Ar/CO/sub 2//Freon gas mixture so as to withstand beam intensities of <or=10/sup 7/ particles/s with efficiency close to 100% and without significant ageing effects. The system, being fully computer- controlled, has a fast diagnostics capability through a powerful software. (3 refs).
