154.1 Introduction RPC [1] was first introduced in the year 1980 by R.Santonico and R. Cardarelli. It is a gaseous detector made up of two high resistive parallel electrode plates e.g. glass, bakelite. RPCs are known to have good time resolution and efficiency to detect charged particles specially muons. INO-ICAL will be using~30,000 RPCs with a time resolution of~ 1 ns in order to study the oscillations in the atmospheric neutrino sector [2]. As a part of R&D, we have developed a large size (240cm x 120cm) single gap (0.2cm) oil free RPC from bakelite sheets available in local market [3, 4].
