Vertical drift chambers for the Hall A high-resolution spectrometers at Jefferson Lab
(2001) In Nuclear Instruments & Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment 474(2). p.108-131- Abstract
- The High-Resolution Spectrometers in Hall A at Jefferson Laboratory have been instrumented with state-of-the-art Vertical Drift Chambers designed and constructed by the Nuclear Interactions Group at MITLNS in conjunction with the Physics Division at Jefferson Lab. These chambers rely on a unique, high cell-density design made possible by the absence of field-shaping wires. Each chamber has an inherent per-plane resolution for 5-cell cosmic-ray tracks of 145 μm FWHM when operated on the bench at -4.8 kV with argon-isobutane gas, and 225 μm FWHM for 5-cell electron tracks when operated in the High-Resolution Spectrometer detector stack at -4.0 kV with argon-ethane gas. The design and construction facilitates wire placement and replacement to... (More)

The design and construction facilitates wire placement and replacement to 50 μm, very low dark current, and no cross-talk. The detectors have been in almost continuous use since April 1996, providing reliable, high-resolution charged-particle tracking data for the Hall A physics program. A complete overview of this project is presented. (Less)
