Two types of MWPC with interpolating cathode pad'' readout for two dimensional position sensitive detection have been studied. One type uses rectangular pads and resistive charge division. A detector with an active area of 26 cm {times} 16 cm, over 1000 readout channels has been built. With readout spacing of 1 cm, a position resolution of {approximately}70{mu}m (rms) for 5.4 keV x-rays and a differential non-linearity of {plus minus}6% have been achieved. Another type of detector uses chevron'' shaped pads for geometrical charge division. Position resolution {approximately}50{mu}m (rms) for 5.4 keV x-rays has been observed in a test detector and results of an investigation to reduce differential non-linearity are reported. 11 refs., 6 figs.
