A simple readout method for MWPCs with high-rate and sub-millimetre resolution

In this work we describe the experimental tests of a new approach to the fast digital readout of MWPCs: electronic subdivision of the cathode strips increases the readout granularity, while a special coding method allows one to extract the address information from a small number of analogue channels with very simple electronics. The principle is demonstrated to be correct and a quite satisfactory performance is observed. This method may help to create economically the large and fast readout systems necessary for high-luminosity colliders and synchrotron radiation research. Also space-borne applications may profit from reduced weight and power requirements. ((orig.))
