At TIFR, we are participating in the development, fabrication and assembly of intricate stepped and non-stepped hole (NSH) frontend electronics boards, baseplates with insulation, and large area Copper-Tungsten (25:75) composite material plates, to be used as an absorber in the electromagnetic section of HGCAL. The overall development employs close interaction with Indian electronics and...
The Forward Calorimeter System (FCS) as well as the Forward Silicon Tracker (FST) is the most recent upgrade of the STAR detector at RHIC, BNL. This upgrade in the forward 2.5<ฮท<4 rapidity region is mainly driven to explore QCD physics in the low region of x as those related to the nucleon spin structure. The FCS consists of the refurbished PHENIX Shashlyk Lead Scinitillator (Pb/Sc)...
The proposed new Electron-Ion collider poses a technical and intellectual challenge for the detector design to accommodate the long-term diverse physics goals envisaged by the program; one requires a 4๐ detector system capable of identifying and reconstructing the energy and momentum of final state particles with high precision. The EPIC collaboration has formed to design, build, and take data...
Muon scattering angle in various materials varies differently due to the multiple Coulomb scattering of incoming muons with materials. The scattering angle mainly depends on the atomic number, the density of the material, and the thickness of the medium at a given energy. Scattering angles at different initial energies also provide the opportunity to classify the scattering angle.In this...
The high granularity calorimeter (HGCAL) of CMS is planned to operate during the high luminosity operation of the LHC (year 2028 onwards), replacing the existing electromagnetic and hadronic calorimeters at the endcap. It will enable a detailed investigation of vector boson fusion processes and Lorentz-boosted topologies at forward rapidity. An extensive validation of the hardware and software...
Liquid argon time-projection chamber (LArTPC) detectors have unique and powerful properties for neutrino physics and beyond-the-standard-model (BSM) searches. A LArTPC provides precise digital readout of charged particle trajectories, enabling a detailed picture of the aftermath of neutrino and BSM particle interactions. We will discusses the opportunity to search for the Beyond Standard model...
In micropattern gas detectors, the Gas Electron Multiplier (GEM) is a proven amplification method for the position detection of ionising radiation, such as charged particles, photons, X-rays, and neutrons. GEM detectors have been used in high energy physics experiments due to their excellent spatial and time resolution, high-rate capabilities, and flexibility in design. The principle is based...
Each High Energy Physics (HEP) experiment has its unique research motivation. The distinctive experimental goals further decides the various set of requirements and design criteria for the front end electronics (FEE) and data acquisition (DAQ) at the back-end. The main purpose of the DAQ is to receive the data with high reliability from the FEE near the HEP detector, and then transfer on to...
Gas Electron Multiplier (GEM) is one of the most suitable gaseous detector for tracking devices in high rate Heavy-Ion (HI) experiments for their high rate handling capability and good spatial resolution.
