چکیده
A new cylindrical low-mass central drift chamber has been constructed for the K + ! + experiment at BNL (E787). The chamber consists of 12 layers of axial wire cells and 6 layers of thin cathode-strip foils, four of which are supported by diierential gas pressure. The momentum resolution (RMS) for muons and pions in the range 150 to 250 MeV/c is found to be about 0.9%.

Tests of Cathode Strip Chamber Prototypes
We report on the results of testing two six-layer 0:6 0:6 m cathode strip chamber (CSC) prototypes in a muon beam at CERN. The prototypes were designed to simulate sections of the end-cap muon system of the Compact Muon Solenoid (CMS) detector which will be installed at the Large Hadron Collider (LHC). We measured the spatial and time resolutions of each chamber for different gains, different o...
متن کاملThe Cathode Strip Chamber Data Acquisition System for CMS
The Cathode Strip Chamber (CSC) [1] Data Acquisition (DAQ) system for the CMS [2] experiment at the LHC [3] will be described. The CSC system is large, consisting of 218K cathode channels and 183K anode channels. This leads to a substantial data rate of ~1.5GByte/s at LHC design luminosity (10cms) and the CMS first level trigger (L1A) rate of 100KHz. The DAQ system consists of three parts. The ...
متن کاملSpatial Resolution Attainable with Cathode Strip Chambers at the Trigger Level
A simple network of comparators applied to the strip signals of a cathode strip chamber allows quick hit localization to within a halfstrip width, or +/a quarter-strip. A six-plane chamber with 6.4 mm wide strips was tested in a high-energy muon beam. The chamber was placed behind a 30 cm thick iron block. We show that patterns of hits localized to within a halfstrip allowed us to identify 300 ...

متن کاملEffect of gas composition on CMS Cathode Strip Chamber performance
Cathode strip chambers (CSCs) are multiwire proportional counters that will be used as muon detectors in the Compact Muon Solenoid (CMS) experiment at the European Center for Nuclear Research (CERN). The composition of the gas inside the chamber influences important chamber parameters, such as gas gain and operational voltage range. Differences in these parameters were examined under variations...
