Abstract:We propose the addition of a Shower Maximum Detector (one plane of 7 vertical slats and another of 8 horizontal slats) to the STAR Zero Degree Calorimeters, closely resembling the ZDC-SMD already used by PHENIX in RHIC run III.  The SMD would add significant capability to STAR in four areas of physics: anisotropic flow, strangelet searching, ultra-peripheral collisions, and spin physics.  The modest funding needed to implement this upgrade has been identified, and an ample manpower effort is available to complete the installation in time for RHIC run IV.
