A prototype of Multi-strip Multi-gap Resistive Plate chamber (MMRPC) with active area 40 cm×20 cm has been developed at SINP, Kolkata as a new Time-Of-Flight (TOF) system with timing resolution σt<120ps and position resolution σx∼0.58cm. The intention is to use multilayers of this type together with converter materials as a high energy neutron (1GeV>En>200MeV) TOF system for the R3B collaboration at the FAIR facility. The design of the detector elements is as follows: a double stack MMRPC with float glass plates and two gas gaps of 0.3 mm per stack. The response of this MMRPC has been studied with cosmic muons and γ-raysγ-rays from a standard radioactive source (60Co) in coincidence with fast inorganic scintillators at SINP laboratory. Recently, response of developed MMRPC has been studied using pulsed electron beam at ELBE, FZD. The details of the MMRPC construction , experimental set-up for investigation of its response and first results are presented.
