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. [...]

Insert your english abstract here.A new versatile facility LEETECH for detector R&D;, tests and calibration is designed and constructed. It uses electrons produced by the photoinjector PHIL at LAL, Orsay and provides a powerful tool for wide range R&D; studies of different detector concepts delivering “monochromatic” samples of low energy electrons with adjustable energy and intensity.

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. [...]
