Precise measurement of internal sense-wire locations in high-energy physics detectors
- Quantum Research Services, Inc., Durham, NC (United States)
Cylindrical straw tubes that contain central sense wires (as anodes) are commonly employed in high-energy and nuclear physics experiments to track charged particles through regions of large detectors. The outer tracking region of the proposed Solenoidal Detector Collaboration (SDC) detector for future experiments at the Superconducting Super Collider (SSC), for instance, is expected to contain more than a hundred thousand 4-mm-diam straw tube drift cells arranged in five cylindrically concentric superlayers. The superlayers will be made up of modules having roughly trapezoidal cross sections. The modules will be up to 4 m long and will contain [approximately]200 straws each, arranged in either six or eight layers. The module shells are expected to be made of thin but nontransparent carbon/epoxy composite material and the straws of mylar or kapton, which has been coated on the inside with a thin ([approx]0.15-[mu]m) layer of copper. A precise knowledge of the locations of the sense wires in these modules is crucial to the intended particle tracking.
