“…The precision achieved in construction has been verified in cosmic ray tests and in the X-ray tomography facility operated at CERN. The result was an average deviation of the wire positions of ≤ 20 µm from the nominal over the full area of the chamber [184,185].…”

“…All chambers delivered to CERN were certified with this or similar methods. Comparison with wire position measurements obtained from X-ray imaging ("tomography", see [63,64]) showed good correlation for the wire displacement in a given chamber, confirming the high accuracy of the cosmic ray method. The noise measurements with and without HV applied to the chamber confirmed expected rates due to cosmic rays respectively inherent amplifier noise.…”

“…By kind permission of Elsevier. (Schuh et al, 2004); optical and capacitive alignment systems, complemented by calibrations on cosmic rays, permit one to reduce the system position errors to a few tens of µm (Cerutti, 2004;Dubbert et al, 2007a). The picture in Figure 11.10 shows a module and monitoring system during assembly.…”
