A time projection chamber with GEM-based readout / LCTPC Collaboration
For the International Large Detector concept at the planned International Linear Collider, the use of time projection chambers (TPC) with micro-pattern gas detector readout as the main tracking detector is investigated. In this paper, results from a prototype TPC, placed in a 1T solenoidal field and read out with three independent Gas Electron Multiplier (GEM) based readout modules, are reported. [...]

Numerical Study of Electrostatic Field Distortion on LPTPC End-Plates based on Bulk Micromegas Modules / Bhattacharya, Purba (NISER, Jatni) ; Bhattacharya, Deb Sankar (Saha Inst. ; IRFU, Saclay) ; Mukhopadhyay, Supratik (Saha Inst.) ; Majumdar, Nayana (Saha Inst.) ; Bhattacharya, Sudeb (Saha Inst.) ; Colas, Paul (IRFU, Saclay) ; Attié, David (IRFU, Saclay)
The R&D; activities for the linear collider TPC (LC-TPC) are currently working on the adoption of the micro pattern devices for the gaseous amplification stage. Several beam tests have been carried out at DESY with a 5 GeV electron beam in a 1 T superconducting magnet. [...]

Performance Studies of Bulk Micromegas of Different Design Parameters / Bhattacharya, P. (Saha Inst.) ; Bhattacharya, Sudeb (Saha Inst.) ; Majumdar, Nayana (Saha Inst.) ; Mukhopadhyay, Supratik (Saha Inst.) ; Sarkar, Sandip (Saha Inst.) ; Colas, Paul (CEA, DSM, Saclay) ; Attie, David (CEA, DSM, Saclay)
The present work involves the comparison of various bulk Micromegas detectors having different design parameters. Six detectors with amplification gaps of 64, 128, 192, 220 μm and mesh hole pitch of 63, 78 μm were tested at room temperature and normal gas pressure. [...]

Investigation of Ion Backflow in Bulk Micromegas Detectors / Bhattacharya, Purba ; Bhattacharya, Deb Sankar ; Mukhopadhyay, Supratik ; Bhattacharya, Sudeb ; Majumdar, Nayana ; Sarkar, Sandip ; Colas, Paul ; Attie, David
The operation of gas detectors is often limited by secondary effects, originating from avalanche-induced photons and ions. Ion backflow is one of the effects limiting the operation of a gas detector at high flux, by giving rise to space charge which disturbs the electric field locally. [...]

Numerical Studies on Time Resolution of Micro-Pattern Gaseous Detectors / Bhattacharya, Purba ; Majumdar, Nayana ; Mukhopadhyay, Supratik ; Bhattacharya, Sudeb
The Micro-Pattern Gaseous Detectors offer excellent spatial and temporal resolution in harsh radiation environments of high-luminosity colliders. In this work, an attempt has been made to establish an algorithm for estimating the time resolution of different MPGDs. [...]

A Comparative Numerical Study on GEM, MHSP and MSGC / Bhattacharya, Purba (Saha Inst.) ; Mukhopadhyay, Supratik (Saha Inst.) ; Majumdar, Nayana (Saha Inst.) ; Bhattacharya, Sudeb (Saha Inst.)
In this work, we have tried to develop a detailed understanding of the physical processes occurring in those variants of Micro Pattern Gas Detectors (MPGDs) that share micro hole and micro strip geometry, like GEM, MHSP and MSGC etc. Some of the important and fundamental characteristics of these detectors such as gain, transparency, efficiency and their operational dependence on different device parameters have been estimated following detailed numerical simulation of the detector dynamics.
