TL;DR: The Large Ion Collider Experiment (ALICE) as discussed by the authors is a general-purpose, heavy-ion detector at the CERN LHC which focuses on QCD, the strong-interaction sector of the Standard Model.

TL;DR: The ALICE Collaboration as mentioned in this paper is a general-purpose heavy-ion experiment designed to study the physics of strongly interacting matter and the quark-gluon plasma in nucleus-nucleus collisions at the LHC.

Abstract: In the framework of an R&D program on the ALICE dimuon trigger system, the spatial resolution of Resistive Plate Chambers working in streamer mode has been investigated during beam tests Preliminary studies with cosmic rays had evidenced a dependence of the charge profile to the high voltage and to the gas mixture However, the spatial resolution measured from the beam tests is only slightly varying with the high voltage and is close to the expected value w/ 12 where w is the strip pitch, for strips of 1 and 2 cm width The probability to fire a strip as a function of the distance from the strip to the particle impact has been measured for various high voltages A simple parametrisation of this probability has been achieved This allows to predict, under various working condition, the cluster size distributions for RPCs with different strip widths and also to account for the effect of the particle incident angle

TL;DR: In this paper, a front-end ASIC for the trigger chambers of the ALICE muon spectrometer under construction at the future LHC at CERN is described and the principle of the ASIC is described.
