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/…
Arbitrary non-paraxial accelerating periodic beams and spherical shaping of light
A. Mathis, F. Courvoisier, R. Giust +4
We report the observation of arbitrary accelerating beams designed using a non-paraxial description of optical caustics. We use a spatial light modulator-based setup and techniques…
Systematic investigation of critical charge limits in Thick GEMs
P. Gasik, L. Lautner, L. Fabbietti +5
We present discharge probability studies performed with a single Thick Gas Electron Multiplier (THGEM) irradiated with alpha particles in Ar-CO and Ne-CO mixtures. We obser…
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…
Charge density as a driving factor of discharge formation in GEM-based detectors
P. Gasik, A. Mathis, L. Fabbietti +1
We report on discharge probability studies with a single Gas Electron Multiplier (GEM) under irradiation with alpha particles in Ar- and Ne-based gas mixtures. The discharge probab…
