Gas Electron Multipliers are recently being used in Time Projection Chamber in ALICE and upcoming sPHENIX experiments. The backwards-drifting Ions , known as Ion Back Flow (IBF) in GEM detectors are undesirable for TPC operation because they distort the uniform electric field in the detector gas volume and hence introducing larger uncertainty in tracking charged particles. For particle...
The sPHENIX experiment at RHIC will be starting its operations in early 2023. It is designed to study heavy ion and proton-proton collisions by measuring hard QCD processes. The Time Projection Chamber (TPC) is used in the sPHENIX detector as one of the main tracking detectors. The Time Projection Chamber (TPC) is used in the sPHENIX detector as one of the main tracking detectors. It is...
The sPHENIX experiment at RHIC requires a high resolution tracking detector in order to
distinguish different states of the Upsilon meson to study the evolution of quark gluon plasma
(QGP). A Time Projection Chamber (TPC) will serve as a main tracking detector for this measurement. The sPHENIX TPC uses a stack of Gas Electron Multipliers (GEMs) as a gain stage
in a reduced ion back-flow...
The sPHENIX detector is under assembly at the Relativistic Heavy Ion Collider (RHIC) at the Brookhaven National Laboratory. It will be commissioned for data taking in 2023. It will focus on measuring jets as well as open and hidden heavy flavor production in heavy ion collisions to study the properties of the Quark Gluon Plasma.
A robust and efficient calibration of the constituting detectors...
The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory (BNL) will collide polarized electrons with polarized proton/ions. The electron Proton and Ion Collider (ePIC) detector is being designed as the day one EIC detector. The EIC physics program requires precision tracking and PID capabilities that extend over a large kinematic acceptance. Micro-Pattern Gaseous Detectors...
The phenomena of transition radiation has been used successfully in several High Energy experiments to discriminate particles with different values of $\gamma$= E/mc$^{2}$ . Traditionally multiwire proportional chambers (MWPC) , longitudinal drift chamber (DC) or straw tubes are being used for Transition Radiation Detector (TRD) which themselves suffer from low rate. Replacing these older...
(for the PICOSEC Collaboration)
PICOSEC was launched as an RD51 "common project" in 2015 with the goal of providing a cost effective, robust solution to charged particle and photon timing for applications with modest track densities. For instance, this is meant to address the "barrel" coverage in future collider experiments at eIC or FCC-ee. In the past year our collaboration has demonstrated...
During the next collisions runs, the Large Hadron Collider (LHC) will deliver instantaneous luminosity in the range 5 $\times$ 10$^{34}$ cm$^{-2}$ s$^{-1}$ to 7 $\times$ 10$^{34}$ cm$^{-2}$ s$^{-1}$, up to 7 times higher than the nominal value. To cope with the higher background rates and to improve the trigger capabilities in the forward region, the muon system of the Compact Muon Solenoid...
The CGEM inner tracker (CGEM-IT) consists of three coaxial layers of triple GEM and is designed to replace the current inner drift chamber of BESIII (BEijing Spectrometer,IHEP, CN), which is suffering from aging.
The tracker is expected to restore efficiency, improve z-determination and secondary vertex position reconstruction with a resolution of 130 μm in the xy-plane and better than 300...
The main goals of the Deep Underground Neutrino Experiment (DUNE) are to measure CP violation in the lepton sector, make precise measurements of neutrino oscillation parameters, observe supernova burst neutrinos, and detect rare processes such as proton decay. To fulfill these goals, DUNE will use a highly capable suite of near detectors. Among the components of the DUNE Near Detector complex...
A next-generation rare pion decay experiment, PIONEER at the Paul Scherrer Institute, is strongly motivated by several inconsistencies between Standard Model (SM) predictions and data pointing towards the potential violation of lepton flavor universality. It aims to measure the difference between decay of pion into electron and muon with a precision of 1 part in 10^4 to study lepton flavor...
Directional 3D reconstruction of low-energy electron recoils is widely applicable, for example to neutrino detection, characterization of the Migdal effect, and X-ray polarimetry. Electron recoils have low charge densities and non-trivial topologies, requiring highly segmented and sensitive MPGD charge readouts. The two leading order effects on the angular resolution of electron recoils in gas...
