Abstract: We have initiated a search for a new type of nuclear matter, the eta-mesic nucleus, using beams from the multi-GeV hadron facility, COSY at Juelich, Germany. A large acceptance scintillator detector, ENSTAR has been designed and built at BARC, Mumbai and fully assembled and tested at COSY. A test run for calibration and evaluation has been completed. In this contribution we present the design and technical details of the ENSTAR detector and how it will be used to detect protons and pions (the decay products of eta-mesic bound state). The detector is made of plastic scintillators arranged in three concentric cylindrical layers. The readout of the detectors is by means of optical fibres. The layers axe used to generate Delta E - E spectra for particle identification and total energy information of stopped particles. The granularity of the detector allows for position (theta and phi) determination making the event reconstruction kinematically complete.
