A new multiplexing scheme for cathode-strip readout chambers

Abstract A multiplexing scheme for cathode strip chamber readouts which is cost-effective and efficient is described. This scheme provides an inexpensive alternative to individual-wire readout schemes, while not compromising the attractive qualities of cathode-strip chambers. A chamber with an area of 72×36 cm was built and tested. A position resolution of 130±50 μm (FWHM) was obtained with the multiplexing scheme. Details of the construction and operation of the cathode-strip chamber and its response to cosmic rays are presented here.
