A modular drift-chamber vertex detector at the CERN ISR

Micro Drift Chamber as a precise vertex detector for the DIRAC experiment

A possible implementation of the Micro Drift Chamber (MDC) technique as a high resolution vertex detector in the upstream part of the DIRAC spectrometer was investigated in this paper. Simulations of different MDC layout were performed with the help of GARFIELD package. Based on the results of simulation the optimal chamber geometry and the gas mixture were selected. One cell prototype was prod...

A Sonic Time Projection Chamber. Sonified Particle Detection at Cern

In a short-term research project at CERN, an auditory display of elementary particle tracks has been developed. Data stems from simulations of the Time Projection Chamber (TPC) in ALICE experiment. Particle detection there is based on pattern recognition algorithms, but is still today double checked with visualization tools. The sonification works with cluster data of the TPC and was designed i...

The 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...

The 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...
