Description

Brookhaven Science Associates, operator of Brookhaven National Laboratory under USDOE Contract DE-AC02-98CH10886 is seeking additional sources for the ALICE TPC PASA (Pre-Amplifier Shaping Amplifier)Chip. The only known source it through CERN in Switzerland. The ALICE TPC PASA (Pre-Amplifier Shaping Amplifier)is an Application Specific Integrated Circuit that implements a 16-channel charge sensitive shaping amplifier. This circuit is conceived and optimized to fulfill the requirements set by the readout of the ALICE TimeProjection Chamber (TPC). The ALICE TPC consists of a cylindrical gas volume (about 90 m3 of Ne-CO2), divided in two drift regions by a high voltage plane located at its axial centre, under a uniform electrostatic field. At the endplates, conventional Multi-Wire Proportional Chambers provide the charge amplification and readout by means of a cathode plane segmented in about 5.7x105 pads. In the MWPC the signal released on the pads is characterized by a fast rise time (less than 1 ns) and a long tail. The amplitude has a typical value of 7 ??A. The signal is delivered on the detector impedance that, to a very good approximation, is a pure capacitance of the order of few pF. The front-end electronics for the ALICE TPC is built on two basic units: the PASA and the ALTRO chips. The latter is a mixed-signal ASIC that integrates 16 channels, each consisting of a 10-bit 25-MSPS ADC, the baseline subtraction, a filter for the cancellation of the signal tail, the zero suppression and a multi-event buffer. The complete readout chain is contained in Front End Cards (FEC), with 128 channels each, connected to the detector by means of capton cables. Additationl information is provided in that attached specification. Interested suppliers should coantact David J. Paveglio
