“…These results indicate that energy resolution of ISMRAN is well described by the standard resolution formula, which is shown in Eqs. 1 and that the photo-statistics term is the primary component of the energy resolution for ISMRAN, which is ∼14%/ √ E bar [1]. Figure 2 (c) shows the nonlinear response of scintillating energy in a single PSB for different radioactive 𝛾-rays sources, that is well described by a fitted parametrization and consistent with the MC predictions.…”

“…The detector setup at Detector Integration Laboratory (DIL) in BARC, consists of 90 PSBs, arranged in an array of 10×9 which is shown in Fig 1 (b) in non-reactor environment. Each PSB is wrapped with Gadolinium Oxide (Gd 2 O 3 ) coated aluminized mylar foils and is 100 cm long with a cross-section of 10×10 cm 2 [1]. Three-inch diameter PMTs are coupled at both ends of each PSB.…”

We report the measurement of the non-reactor environmental backgrounds and the detector response with the Indian Scintillator Matrix for Reactor Anti-Neutrinos (ISMRAN), which is ∼1 ton detector setup by volume, consisting of 10×9 (10 rows and 9 columns) Plastic Scintillator Bars (PSBs) array at BARC, Mumbai, India. ISMRAN is an above-ground anti-neutrino (𝜈 𝑒 ) experiment at very short baseline located at Dhruva research reactor facility. It is enclosed by a shielding made of 10 cm thick lead and 10 cm thick borated polyethylene to minimize the backgrounds and is mounted on a movable base structure, situated at ∼ 13 m away from the reactor core. These measurements are useful in the context of the ISMRAN detector setup that will be used to detect the reactor 𝜈 𝑒 and measure its energy spectrum through the inverse beta decay (IBD) process. In this paper, we present the energy resolution model and energy non-linearity model of PSB and the cosmogenic muon-induced background, based on the sum of their energy depositions and number of hit bars. Reconstructed sum energy spectrum and number of hit bars distribution for 22 Na radioactive source has been compared with Geant4 based Monte Carlo simulations. These * Speaker

“…3 (a), (b), and (c) panels. The results are compared with simulations using Geant4 where the detector geometry, physics processes for different interactions and implementation of digitization of the energy deposition in each bar is performed to get a reasonable agreement with the measured data [14]. The uniformity of the response among all the PSBs is estimated to be within ∼2%.…”

Indian Scintillator Matrix for Reactor Anti-Neutrino (ISMRAN) experiment is the first indigenous effort in the country to measure the reactor based antineutrinos at very close distances (∼13 m) from the reactor core. The experiment is setup in DHRUVA research reactor and has been in the data taking mode since January 2022. The main goal of ISMRAN is to understand the Reactor Anti-neutrino Anamoly from a reactor core, which utilizes natural uranium as fuel. All previous measurements are performed using highly enriched 235 U fuel and observed a deficit of 4-6% in the antineutrino yield when compared with theory predictions. In this proceedings, we present first results from the complete ISMRAN setup at DHRUVA reactor hall. We will summarize the foreground activities that were carried out for the understanding of the ISMRAN detector response. A new generation of experiments for future, involving the measurement of reactor antineutrinos using coherent elastic scattering will also be discussed.
