“…A set of four fast plastic scintillators (Saint Gobains BC-404) was used for the muon flux measurement. Each scintillator, having dimensions of 96.4 cm × 32.1 cm × 1 cm, was coupled to a 50 mm diameter photomultiplier (ET Enterprises 9807B) using wavelength shifting (WLS) optical fibers running along the length of the upper surface [18]. The scintillators were placed in a vertical stack, as shown in Fig.…”

Ambient radiation background contributed by the penetrating cosmic ray particles and the radionuclides present in the rock materials have been measured at an underground laboratory located inside a mine at 555 m depth.The laboratory is being set up to explore rare event search processes, such as direct dark matter search, neutrinoless double beta decay, axion search, supernova neutrino detection, etc., that require specific knowledge of the nature and extent of the radiation environment in order to assess the sensitivity reach and also to plan for its reduction for the targeted experiment. The gamma ray background, which is mostly contributed by the primordial radionuclides and their decay chain products, have been measured inside the laboratory and found to be dominated by rock radioactivity for E γ 3 MeV. Shielding of these residual gamma rays for the experiment was also evaluated. The cosmic muon flux, measured inside the laboratory using large area plastic scintillator telescope, was found to be: (2.051 ± 0.142 ± 0.009) × 10 −7 cm −2 .sec −1 , which agrees reasonably well with simulation results. The neutron background flux has been measured for the radiogenic neutrons and found to be: (1.61 ± 0.03) × 10 −4 cm −2 .sec −1 for no threshold cut. Detailed GEANT4 simulation for the radiogenic neutrons and the cosmogenic neutrons have been carried out. Effects of multiple scattering of both the types of neutrons within the surrounding rock and the cavern walls were studied and the results for the radiogenic neutrons are found to be in reasonable agreement with experimental results. Neutron fluxes contributed by those neutrons of cosmogenic origin have been reported as function of the energy threshold.

“…The 4 m×4 m×1.1 m mini-ICAL magnet with 11 iron layers, and 2 m×4 m×1.1 m active detector using 20 RPCs which is housed in the central region of the magnet, have been in operation for about 4 years and collecting cosmic muon data. A modest, proof-of-principle cosmic muon veto detector (CMVD) of about 1 m×1 m×0.3 m dimensions was set up a few years ago, using scintillator paddles [2]. The measured cosmic muon veto efficiency of ∼99.98% and simulation studies of muon induced background events in the ICAL detector surrounded by an efficient veto detector were promising enough to perform simulation studies for a shallow depth ICAL detector, surrounded by a 99.99% efficient CMVD, placed at a depth of 100 m [3].…”

A 51-kiloton magnetised Iron Calorimeter (ICAL) detector, using Resistive Plate Chambers (RPCs) as active detector elements, aims to study atmospheric neutrinos. A prototype -1/600 of the weight of ICAL, called mini-ICAL was installed in the INO transit campus at Madurai. A modest proof-of-principle cosmic muon veto detector of about 1 m×1 m×0.3 m dimensions was setup a few years ago, using scintillator paddles. The measured cosmic muon veto efficiency of 99.98% and simulation studies of muon-induced background events in the ICAL detector surrounded by an efficient veto detector were promising. This led to the idea of constructing a bigger cosmic muon veto around the mini-ICAL detector. Details of the design, fabrication, quality control and construction of the detector including the electronics, trigger and DAQ systems planned will be briefly presented.
