Abstract
The first implementation of a position sensitive readout for a Micro Hole and Strip Plate (MHSP) is described and tested. The readout consists on a resistive layer crossing the anodes and connected to a preamplifier on each side. By weighing the charge pulses on both preamplifiers it is possible to determine the interaction point. A 100-200 Ω resistance layer between consecutive strips was found to be the best compromise between position linearity and energy resolution. Preliminary results using 22.1 keV X-rays present a good linearity between the measured and the actual position with a mean deviation of about 0.15 mm and a position resolution of 1.6 mm full-width at half-maximum (FWHM), being limited by the analogue division electronic circuit. The performance of the MHSP position detector will be presented and discussed for 1D readout.
