The HERMES Back Drift Chambers
نویسنده
چکیده
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 a discussion of the experience gained through the rst three years of operation.

Multiwire proportional chambers in the HERMESexperimentA
The multiwire proportional chambers of the HERMES spectrometer are described. The chambers are located in the spectrometer magnet gap which imposed strong constraints on their design. Non-ammable gas mixture of Ar(65%), CO 2 (30%) and CF 4 (5%) is successfully used with an eeciency plateau 500V wide. The readout is performed by means of the recently developed LeCroy PCOS4 acquisition system upg...
متن کاملun 2 00 1 The Drift Chambers Of The Nomad Experiment
We present a detailed description of the drift chambers used as an active target and a tracking device in the NOMAD experiment at CERN. The main characteristics of these chambers are a large area (3 × 3 m2), a self supporting structure made of light composite materials and a low cost. A spatial resolution of 150 μm has been achieved with a single hit efficiency of 97% . 1 on leave from the Labo...

متن کاملLimits on the Accuracy of Drift Chambers and Calibration Beams
years from now. The understanding of intrinsic limits on the spatial accuracy of drift chambers, and the development of new methods for calibrating them, are therefore still relevant. The present talk attempts to review the state of the art. In order to see what are the main questions to be asked, I have summarized in Table 1 the main characteristics of the drift-chamber detectors proposed for ...
متن کاملProperties 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.
