Correction of the baseline fluctuations in the GEM-based ALICE TPC
/ ALICE TPC Collaboration
To operate the ALICE Time Projection Chamber in continuous mode during the Run~3 and Run~4 data-taking periods of the Large Hadron Collider, the multi-wire proportional chamber-based readout was replaced with gas-electron multipliers. As expected, the detector performance is affected by the so-called common-mode effect, which leads to significant baseline fluctuations. [...]

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. [...]

The upgrade of the ALICE TPC with GEMs and continuous readout
/ ALICE TPC Collaboration
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 describe the design of new readout chambers and front-end electronics, which are driven by the goals of the experiment. [...]

SAMPA Chip: the New 32 Channels ASIC for the ALICE TPC and MCH Upgrades
/ Adolfsson, J (Lund U.) ; Pabon, A Ayala (Sao Paulo U.) ; Bregant, M (Sao Paulo U.) ; Britton, C (Oak Ridge) ; Brulin, G (Orsay, IPN) ; Carvalho, D (Sao Paulo U.) ; Chambert, V (Orsay, IPN) ; Chinellato, D (Campinas State U.) ; Espagnon, B (Orsay, IPN) ; Herrera, H D Hernandez (Sao Paulo U.) et al.
This paper presents the test results of the second prototype of SAMPA, the ASIC designed for the upgrade of read-out front end electronics of the ALICE Time Projection Chamber (TPC) and Muon Chamber (MCH). SAMPA is made in a 130 nm CMOS technology with 1.25 V nominal voltage supply and provides 32 channels, with selectable input polarity, and three possible combinations of shaping time and sensitivity.
