| Abstract | : | It is proposed to integrate the WA98 preshower Photon Multiplicity Detector (PMD) with some modifications into the STAR Experiment to study photon produciton and isospin fluctuations in nucleus- nucleus collisions at RHIC energy in order to investigate the formation of Quark-Gluon Plasma (QGP), the dynamics of hadronization process, the characteristics of the hot hadron gas and to search for Disoriented Chiral Condensates (DCCs). The PMD, to be mounted at 7m from vertex, will have fine granularity and almost full azimuthal coverage in the pseudo-rapidity region 2.0 < eta < 3.8. Simulation results are presented to describe the effectiveness of the proposed detector to measure photon multiplicity on event-by-event basis in the actual environment of the STAR experiment. We show that the PMD can provide reasonable selection on low pt photons suitable for DCC searches and also estimates of global transverse electromagnetic energy.
