Design 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...
متن کاملDevelopment of a straw tube chamber with pickup-pad readout
We have developed a straw tube chamber with pickup-pad readout. The mechanism for signal pickup, the size of the pickup signal, and the distribution of signals among neighboring pads are discussed. We have tested a prototype chamber in a beam test at Brookhaven National Laboratory and have measured chamber e$ciencies in excess of 99%. ( 1999 Elsevier Science B.V. All rights reserved.

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 Charge Distribution on the Cathode of a Straw Tube Chamber
A straw tube chamber is a low-cost version of a proportional counter. These devices consist of a pair of coaxial conducting cylinders with the region between the cylinders filled with a gas such as argon. The inner cylinder of radius a is the anode, and is held at potential V ; the outer cylinder of radius b is the cathode, and is grounded. If a penetrating charged particle passes through the c...
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...
