Double-hit separation and dE/dx resolution of a time projection chamber with GEM readout
Yumi Aoki, David Attié, Ties Behnke +68
A time projection chamber (TPC) with micropattern gaseous detector (MPGD) readout is investigated as main tracking device of the International Large Detector (ILD) concept at the p…
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…
Comparison of Bulk Micromegas with Different Amplification Gaps
Purba Bhattacharya, Sudeb Bhattacharya, Nayana Majumdar +4
The bulk Micromegas detector is considered to be a promising candidate for building TPCs for several future experiments including the projected linear collider. The standard bulk w…
First measurement of polarisation asymmetry of a gamma-ray beam between 1.74 to 74 MeV with the HARPO TPC
Philippe Gros, Sho Amano, David Attié +23
Current -ray telescopes suffer from a gap in sensitivity in the energy range between 100keV and 100MeV, and no polarisation measurement has ever been done on cosmic sources abo…
The International Linear Collider. A European Perspective
Philip Bambade, Ties Behnke, Mikael Berggren +31
The International Linear Collider (ILC) being proposed in Japan is an electron-positron linear collider with an initial energy of 250 GeV. The ILC accelerator is based on the techn…
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…
