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 کاملThe High-density Multiwire Drift Chamber
A multiwire propor t ional chamber , with a high-densi ty drift space at tached, has been developed as a posit ion-sensit ive detector for nonioniz ing radiat ion. A chamber with a 5 g /cm a d r i f t s p a c e , compris ing a l eadb i smuth matr ix o f 1 m m square holes on a 1.5 m m pi tch has been investigated. For 0.66 MeV pho tons a detection efficiency o f 5%, combined with a spatial reso...
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 کاملDesign of the CHIRON high-resolution spectrometer at CTIO
Small telescopes coupled to high resolution spectrometers are powerful tools for Doppler planet searches. They allow for high cadence observations and flexible scheduling; yet there are few such facilities. We present an innovative and inexpensive design for CHIRON, a high resolution (R~80.000) Echelle spectrometer for the 1.5m telescope at CTIO. Performance and throughput are very good, over t...
متن کاملDrift-Chamber Gas System Controls Development for the CEBAF Large Acceptance Spectrometer
The CEBAF Large Acceptance Spectrometer (CLAS) is a superconducting toroidal magnet with a large volume of drift chambers for charged particle tracking. The performance of these chambers depends on accurate monitoring and control of the mixture, flow rate, pressure, temperature, and contaminant levels of the gas. To meet these requirements, a control system is being developed with EPICS. The in...
