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 Time-Projection Chamber (TPC) as discussed by the authors is the main device for pattern recognition, tracking, and identification of charged particles in the ALICE experiment at the CERN LHC.

TL;DR: The BRAHMS experiment at RHIC was conceived to pursue the understanding of nuclear matter under extreme conditions by detailed measurements of charged hadrons over the widest possible range of rapidity and transverse momentum as discussed by the authors.

TL;DR: In this article, the design of the pulsed UV laser and optical system, together with the control and monitoring systems, is presented, and the alignment of the read-out chambers is performed, and variations of the drift velocity due to drift field imperfections can be measured and used as calibration data in physics data analysis.

TL;DR: In this article, the basic principles of operating the 266 nm laser are presented, showing the installation and adjustment of the optical system and describing the control system, and the first tracks were observed both from the cosmic ray muons and from the laser rays injected into the TPC.
