The Mi's Ii Drift Chamber System*
The MPS II detectors are narrow drift space chambers designed for high position resolution in a magnetic field and in a very high particle flux environment. Central to this implementation was the development of 3 multi-channel custom IC's and one multi-channel hybrid. The system is deadtimeless and requires no corrections on an anode-to-anode basis. Operational experience and relevance to ISABE...
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 کاملThe Time Expansion Chamber as High Precision Drift Chamber
With the principle of the time expansion chamber and the additional measurement of the position of the avalanche along the circumference of the anode wire it is possible to reconstruct the spatial distribution of the primary ionization in space. A position resolution for minimum ionizing tracks of a 5 30 urn is expected. First tests and concepts for vertex detectors are presented.
متن کاملNew Drift Chamber for - the Mark Ii
A new cylindrical drift chamber is being constructed for the Mark lI detector for use at the new SLAC Linear Collider. The design of the new chamber is based on a multi-sensewire cell of the jet-chamber type. In addition to driitime measure men@ pulse height measurements from the sense wires will provide electron-hadron separation by dE/dz. The design and construction of the chamber, tests of p...
