A detailed numerical simulation has been performed to investigate the timing properties of a standard RPC geometry in order to optimize its application in INO-ICAL experiment designed for studying atmospheric neutrinos. The timing information provided by the RPC is an important observable in the experiment to determine the direction of the neutrinos. Effects of various operating conditions and design components on the RPC timing response, mainly the average signal arrival time and the time resolution have been studied in this context. The dependence of the detector efficiency on the same parameters has also been presented.

“…In order to investigate the source of inefficiency of CMV, the plastic paddles used in constructing the CMV huts were placed in the 12 layer RPC (1m × 1m) stack detecting cosmic muons [9] to measure the local inefficiency for muon detection as a function of X-Y position. The muon trigger was generated by the coincidence of layers 4, 5, 6 and 7 with a trigger rate of ∼50 Hz, the efficiency for a 320 mm × 320 m pixel can be measured to about 0.17% accuracy in a day.…”

A: The motivation for a cosmic muon veto (CMV) detector is to explore the possibility of locating the proposed large Iron Calorimeter (ICAL) detector at the India based Neutrino Observatory (INO) at a shallow depth. An initial effort in that direction, through the assembly and testing of a ∼1 m × 1 m × 0.3 m plastic scintillator based detector, is described. The plan for making a CMV detector for a smaller prototype mini-ICAL is also outlined.

“…These RPC detectors will be placed in between two Iron plates of thickness 56 mm with a gap of 40 mm [1]. Each of these RPC detectors will consist of two orthogonally placed (one above the RPC gas chamber and other will be below the RPC gas chamber) readout strip panel with respect to each other, in order to record particle hit coordinates in both X and Y planes [2] [3]. Therefore, near about 60,000 readout strips panels which will be used in this experimental setup to pick up the signals generated in the gas chamber due to ionization of the gas [2].…”

The India based Neutrino Observatory (INO) is a mega science project of India, which is going to use near about 30, 000 Resistive Plate Chambers (RPC) as active detector elements for the study of atmoshpheric neutrino oscillations. Each RPC detector will consist of two orthogonally placed readout strips panel for picking the signals generated in the gas chamber. The area of RPC detector in INO-ICAL (Iron Calorimeter) experiment will be 2m × 2m, therefore the dimension of readout strips panel will also be of 2m × 2m. To get undistorted signals pass through the readout strips panel to frontend electronics, their Characteristic Impedance should be matched with each other. For the matching of Characteristic Impedance we have used the principle of termination. In the present paper we will describe the need and search of new dielectric material for the fabrication of flame resistant, waterproof and flexible readout pickup strips panel. We will also describe the measurement of Characteristic Impedance of plastic honeycomb based readout strips panel and Silicon Fiber sheet based readout strips panel in a comparative way, and its variation under loading and with time.
