N2 - Conventional MSGCs are made of metal electrodes that might absorb or reflect optical photons. If the electrodes are made of transparent material like ITO, we could take advantage of optical readout. A gas scintillation proportional counter made of ITO MSGC is fabricated and tested where both optical and charge signals are obtained. We have selected a multi-grid structure that can avoid charge-up problem with normal transparent glass substrate. Test results with Ar and CF4 gas mixture showed a stable gas gain of ∼2800 and ∼110 optical photons for 6 keV X-rays. Position sensing with PSPMT has successfully been demonstrated.
