111. Ion Back Flow and Energy Resolution study for Quadruple GEM detector

Sourav Tarafdar (Vanderbilt University)

WG5: MPGDs

Contribution Talk

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...

Contribution Talk

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...

141. Spark Monitoring System for sPHENIX TPC GEMs

WG5: MPGDs

Contribution Talk

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...

177. TPOT: Micromegas detectors to reconstruct distortions in the TPC for the sPHENIX experiment

WG5: MPGDs

Contribution Talk

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...

121. An overview of the MPGD Development for the EIC’s ePIC Detector

Matt Posik (Temple University)

WG5: MPGDs

Contribution Talk

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...

109. Particle Identification using GEM based TRD/T

WG5: MPGDs

Contribution Talk

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...

58. Recent Results from PICOSEC:Sub-25 Picosecond MPGD based charged particle timing

Contribution Talk

(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...

40. First performance of Triple-GEM detectors in the CMS muon system with cosmic rays and LHC collisions

Contribution Talk

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...

39. Detector and electronics integration for the CGEM Inner Tracker

Ilaria Balossino

WG5: MPGDs

Contribution Talk

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...

106. A Gaseous Argon-Based Near Detector for DUNE

WG5: MPGDs

Contribution Talk

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...

135. A tracker for PIONEER

WG5: MPGDs

Contribution Talk

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...

103. 3D reconstruction of low-energy electron recoils in gas Time Projection Chambers with MPGD charge readouts

WG5: MPGDs

Contribution Talk

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...
