TL;DR: The Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) at CERN as mentioned in this paper was designed to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1)

TL;DR: In this paper, the authors developed an automatic charge amplifier output voltage offset compensation system which operates regardless of the cause of the offset (detector or electronic) and the main performances of the system are the following: the input equivalent noise charge is 190 e rms (input non-connected, peaking time 500 nns), the highest gain is 255 mV/fC, the peak time is adjustable between 200 nns and 2μs and the power consumption is 10 mW per channel.

TL;DR: In this article, the results of test results of Gas Electron Multiplier (GEM) coupled with a MSGC in October 1997 are described, and several studies have been realized in a beam of Minimum Ionizing Particles (100 ǫ/c muons): signal-to-noise curves for different GEM amplifications and drift fields, spatial resolution, efficiency and cluster size.

TL;DR: The distributed data acquisition (DAQ) system developed by the GRPHE group is a combination of hardware and software dedicated to high energy physics and is used in the beam tests of the CMS tracker.

TL;DR: The trigger of the first CMS tracking milestones is a dedicated system for analog multiplexed front end electronics with coupling with a multi-crate disributed DAQ system to reach a high scalability of experiment subsystems and performance for test beams.
