[en] An apparatus for measurement of the space profiles of particle beams by means of two-coordinate chambers (16 electrodes per coordinate) is described. The working current range is 10^-9-10^-6 A per electrode. A current integrator is connected to each electrode. After completion of a measurement cycle, the charges that have been accumulated in the integrators are successively converted to digital code and sent to a personal computer. 5 refs., 4 figs
