Performance of the SLD Central Drift Chamber
We reportfor thefirsttimeon theperformanceof theSLD Central Drift Chamber (CDC) at SLC, which has been recordingdatasince 1992. The low mass of the chamber and the use-of a gas characterized by both a low drift velocity and low diffusion constant help to minimize the drift-distance measurement errors. We describe some of the calibrations and corrections applied to the dam, and report on the res...
متن کاملRadiation Aging Studies of Co2 Hydrocarbon Mixtures for the Sld Drift Chamber*
The SLD drift chamber requires a ‘slow’ drifting gas and low diffusion to allow wave form digitization. CO2 provides this but requires an admixture of a quencher to provide more gain. _ A test chamber with an 8 sense wire cell, such as will appear in the final chamber, was exposed to an X-ray tube while containing a variety of binary admixtures of COz: 8% isobutane, 8% ethane, and 2% isopropano...
متن کاملThe BaBar Drift Chamber
The central drift chamber for the BaBar detector at the PEP-II Bfactory at SLAC is a cylindrical chamber with a length of 280 cm and outer radius of 81 cm. It consists of 40 layers of small hexagonal cells arranged in 10 axial and stereo super-layers. In order to minimize multiple scattering, light materials are used for the mechanical structure, and the gas mixture is Helium based. The pulse-h...
متن کاملThe BaBar drift chamber project
The BaBar Drift Chamber is now under construction. We review its design, the progress in the construction of the components, the plan for assembly and stringing and we present test results obtained with a prototype exposed at SLAC to cosmic rays. We also report on projected dE/dx performance from beam tests done with a chamber with a different cell design. ( 1998 Published by Elsevier Science B...
متن کاملDesign and performance of a straw tube drift chamber
Drift chambers are now used in a lmost every h igh energy physics experiment. There are many different designs of drift chambers and one of them uses straw tubes as detector elements [1]. In this article, we repor t the design, construct ion, and per formance of large straw tube drift chambers used in the spect rometer a rm of E735 at the Fermi lab collider. E735 is an exper iment to s tudy low...
