Properties and performances of a frontend ASIC prototype for the readout of the CMS Barrel Muon Drift Tubes Chambers

A frontend Application Specific Integrated Circuit (ASIC) prototype developed for the read out of the CMS barrel muon drift tubes chambers has been produced in 100 samples. Several chips were used to read out one superlayer (224 drift tubes) of a full size prototype chamber. The properties of the chips and the performance of the chamber part equipped with the frontend prototype are presented.

Slow Control for Micromegas and Drift Chambers

A new spectrometer is being built for the COMPASS particle physics experiment at CERN. Saclay is in charge of the construction and the operation of two types of gaseous detectors: Micromegas microstrip detectors and Drift chambers [1], [2]. The operation of the detectors requires the slow control of high voltages and currents, and of the thresholds for the Front-End. This control system has bee...

The HERMES Back Drift Chambers

The tracking system of the HERMES spectrometer behind the bending magnet consists of two pairs of large planar 6-plane drift chambers. The design and performance of these chambers is described. This description comprises details on the mechanical and electronical design, information about the gas mixture used and its properties, results on alignment, calibration, resolution, and e ciencies, and...
