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...
متن کاملPhysical Aspects of Charged Particle Track Structure
A plasmon generated by a swift charged particle constitutes a coherent excitation about the particle track. We discuss the physics of the plasmon in conden~ed m.atter and its e~ects on ele~tr?n transport in liquid water. Criteria for the existence of the plasmon III a given substance, Its chara~teflsttcs when generated by a swift charged particle, its representation in impact parameter space, a...
متن کاملA Sonic Time Projection Chamber. Sonified Particle Detection at Cern
In a short-term research project at CERN, an auditory display of elementary particle tracks has been developed. Data stems from simulations of the Time Projection Chamber (TPC) in ALICE experiment. Particle detection there is based on pattern recognition algorithms, but is still today double checked with visualization tools. The sonification works with cluster data of the TPC and was designed i...
متن کاملOptical Readout Time Projection Chamber (O-TPC) for a Study of Oxygen Formation In Stellar Helium Burning
We are developing an Optical Readout Time Projection Chamber (O-TPC) detector for the study of the 1̧2ag reaction that determines the ratio of carbon to oxygen in helium burning. This ratio is crucial for understanding the final fate of a progenitor star and the nucleosynthesis of elements prior to a Type II supernova; an oxygen rich star is predicted to collapse to a black hole, and a carbon ri...
