Impact of the gas choice and the geometry on the breakdown limits in Micromegas detectors
P. Gasik, T. Waldmann, L. Fabbietti +3
In this study we investigate the stability limits of Micromegas detectors upon irradiation with alpha particles. The results are obtained with meshes with different optical transpa…
New (TH)GEM coating materials characterised using spectroscopy methods
B. Ulukutlu, P. Gasik, T. Waldmann +5
In this work GEM and single-hole Thick GEM structures, composed of different coating materials, are studied. The used foils incorporate conductive layers made of copper, aluminium,…
The upgrade of the ALICE TPC with GEMs and continuous readout
J. Adolfsson, M. Ahmed, S. Aiola +232
The upgrade of the ALICE TPC will allow the experiment to cope with the high interaction rates foreseen for the forthcoming Run 3 and Run 4 at the CERN LHC. In this article, we des…
High voltage scheme optimization for secondary discharge mitigation in GEM-based detectors
L. Lautner, L. Fabbietti, P. Gasik +1
We investigate the influence of the high voltage scheme elements on the stability of a detector based on a single cm area GEM with respect to the secondary dischar…
Secondary discharge studies in single and multi GEM structures
A. Deisting, C. Garabatos, P. Gasik +12
Secondary discharges, which consist of the breakdown of a gap near a GEM foil upon a primary discharge across that GEM, are studied in this work. Their main characteristics are the…
Particle identification studies with a full-size 4-GEM prototype for the ALICE TPC upgrade
M. M. Aggarwal, Z. Ahammed, S. Aiola +177
A large Time Projection Chamber is the main device for tracking and charged-particle identification in the ALICE experiment at the CERN LHC. After the second long shutdown in 2019/…
