Measurement and simulation of two-phase CO cooling for the AFTER electronics of the Micromegas modules for a Large Prototype of a Time Projection Chamber
Deb Sankar Bhattacharya, David Attie, Paul Colas +6
The readout electronics of a Micromegas (MM) module consume nearly 26 W of electric power, which causes the temperature of electronic board to increase upto .…
Experimental and numerical simulation of a TPC like set up for the measurement of ion backflow
Deb Sankar Bhattacharya, Purba Bhattacharya, Prasant Kumar Rout +8
Ion backflow is one of the effects limiting the operation of a gaseous detector at high flux, by giving rise to space charge which perturbs the electric field. The natural ability…
Performance Studies of Bulk Micromegas of Different Design Parameters
Purba Bhattacharya, Sudeb Bhattacharya, Nayana Majumdar +4
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 ~μ\mat…
Investigation of Ion Backflow in Bulk Micromegas Detectors
Purba Bhattacharya, Deb Sankar Bhattacharya, Supratik Mukhopadhyay +5
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…
