It is based on a multi-wire proportional counter (MWPC) using a delay-line readout method. The MWPC, necessary for recording plasma image data, provides the combined advantages of low neutron radiation sensitivity and large sensitive detection area. The fabricated PSD for the XICS is a four-segment MWPC that can be used in intense X-ray photon environments. PACS numbers: 29.40.Cs, 52.70.-m
