Deep-learning tools are being used extensively in high energy physics and becoming central the reconstruction of neutrino interactions particle detectors. In this work, we report on performance a graph neural network assisting with set event reconstruction. The three-dimensional tracks produced can be subject to ambiguities due multiplicity signatures detector or leakage signal between neighbor...

In this paper, we propose a method to determine the equilibrium factor using a bare LR 115 detector. The partial sensitivities rhoi of the LR 115 detector to 222Rn and its alpha-emitting short-lived progeny, 218Po and 214Po, were investigated. We first determined the distributions of lengths of major and minor axes of the perforated alpha tracks in the LR 115 detector produced by 222Rn, 218Po a...

background: radon, thoron and their progenies are the most important contributions to human exposure from natural sources. radon exists in soil gas, building materials, indoor atmosphere etc. among all the natural sources of radiation dose to human beings, inhalation of radon contributes a lot. the work presented here emphasizes the long term measurements of radon, thoron and their progeny conc...

In this contribution we present new developments and results for the LIT track reconstruction package for CBM in the CbmRoot framework. The reconstruction package is organized to be flexible with respect to feasibility studies of different physics channels and to optimization of the detector geometries. The tracking software has been redesigned to make it more general and to simplify the suppor...

I am happy to announce today that the Department’s proposal to set up a Dr Homi Bhabha National Institute has been approved. This will bring together ten premier institutions all over the country under a single research-driven framework. This will help ensure that our scientists and our scientific establishments remain at the forefront of the pursuit of excellence, comparable with the best glob...

It was with great emotion that I accepted to be a guest speaker to this memorial section dedicated to my old-time friend, Prof. Radomir Ilić. In addition to being one of the most outstanding scientists in the field of nuclear tracks, Prof. Radomir Ilić has been always highly acclaimed by the scientific community for his enthusiasm, his warm friendship, and his great vitality. Through his succes...

Every large ICF laser facility, including Nova, OMEGA, and GEKKO, uses neutron time-of-flight (nTOF) systems to measure neutron yields and ion temperatures. Such nTOF systems are usually based on current-mode detectors consisting of a fast plastic scintillator optically coupled to a fast photomultiplier tube (PMT). A high-bandwidth transient digitizer records the signal. These systems, which ar...

Recent efforts have been made to improve the prompt fission neutron spectrum and nu-bar measurements for Uranium and Plutonium isotopes particularly in the keV region. A system has been designed at Rensselaer Polytechnic Institute (RPI) utilizing an array of EJ-301 liquid scintillators as well as lithium glass and plastic scintillators to experimentally determine these values. An array of BaF2 ...

The effects of UVC exposure on the track etch rate Vt and the detector sensitivity V of CR-39 SSNTDs were investigated through the diameters and depths of alpha-particle tracks. Both the bulk etch rate Vb and Vt increased but V decreased. The track diameters and depths were used to derive a V function for CR-39 detectors with and without UV irradiation. © 2008 Elsevier Ltd.
