The ALICE detector is a dedicated heavy-ion detector currently built at the Large Hadron Collider (LHC) at CERN. The detector control system (DCS) covers the task of controlling, configuring and monitoring the detector. One subsystem is the control system for the front-end electronics of the time projection chamber (TPC). It controls in total 216 readout system with 4356 front-end cards serving roughly...
The Alice time projection chamber (TPC) detector will be operated with a gas mixture of 90% Ne and 10% CO2 at the electric field of 400 V/cm. Recent studies favor a three-component mixture by adding about 5% N2, which will improve the stability of the gas against discharges. These operating parameters lead to a nonsaturated drift velocity for electrons but also impose that all external influences...
