Description
The INO-ICAL is a proposed neutrino physics experiment in which RPCs are used as active detecting medium. Construction of an Iron Calorimeter (ICAL) detector for studying Neutrinos, consisting of 50Kton of magnetized iron plates arranged in stacks with gaps in between RPCs would be inserted as active detectors, the total number of 2m × 2m RPCs being about 29000. But for 2m×2m normal glass with thickness 3mm is difficult and risky to handle at the time of making RPCs. So this time we made the RPC with toughened glass and characterize it. Toughened or tempered glass is a type of glass processed by controlled thermal or chemical treatments in local glass industry to increase its strength compared with normal glass. This paper compares the characteristics of RPC, e.g., noise rate, dark current, efficiency etc of this toughened glass and of normal glass.
