Readout Electronics for the ALICE Time Projection Chamber
In this paper we present the architecture of the Readout Electronics for the Time Projection Chamber (TPC) of the ALICE experiment at CERN LHC. The ALICE TPC electronics consists of 557568 channels. A single readout channel is made of two basic units: (a) an analogue ASIC (PASA) that incorporates the shaping/amplifier circuits for 16 channels; (b) a mixed-signal ASIC (ALTRO) that integrates 16 ...
متن کاملPerformance of a Time-Projection-Chamber with a Large-Area Micro-Pixel-Chamber Readout
A micro time-projection-chamber (micro-TPC) with a detection volume of 23×28×31 cm was developed, and its fundamental performance was examined. The micro-TPC consists of a micro pixel chamber with a detection area of 31×31 cm as a two-dimensional imaging device and a gas electron multiplier with an effective area of 23×28 cm as a pre-gas-multiplier. The micro-TPC was operated at a gas gain of 5...

We describe the readout electronics for the STAR Time Projection Chamber. The system is made up of 136,608 channels of waveform digitizer, each sampling 512 time samples at 6-12 Mega-samples per second. The noise level is about 1000 electrons, and the dynamic range is 800:1, allowing for good energy loss (dE/dx) measurement for particles with energy losses up to 40 times minimum ionizing. The s...
متن کاملDetector Control System for the ALICE Time Projection Chamber
The Alice experiment is operated by a hierarchical structure of control layers. The various sub-detectors of the ALICE experiment are controlled by the Detector Control System (DCS). The topmost layer is the Experimental Control System (ECS) and controls the DCS, Data Acquisition (DAQ) and Trigger system (Figure 1). During normal operation the shift crew controls the detector at the ECS level. ...
متن کاملThe TESLA Time Projection Chamber
TESLA (TeV-Energy Superconducting Linear Accelerator) is an ee linear Collider designed to operate in the energy range beyond the mass of the Z and up to the TeV region. If approved, TESLA would allow a wide physics program, focusing among other things on precision tests of the established Standard Model, the Higgs mechanisms and the discovery of new particles. To optimally exploit the physics ...
