This report outlines the current status of the Muon Alignment Project, co-convened by Gervasio Gomez and James Pivarski, as of September 26, 2014. The primary focus is to resolve discrepancies between hardware measurements and tracking estimates. Experts are currently evaluating potential CSC chamber positions derived from laser alignment and disk surveys, with particular attention to inconsistencies in the Z-sensor array and difficulties in determining RotY. The project also aims to validate transfer lines and sensor positions, targeting initial results by the end of July.

James N. Bellinger 26 September 2014 Muon Alignment Project Status • Gervasio Gomez and James Pivarski are co-conveners • Current priority of group is to understand apparent conflict between hardware and tracking estimates of DT • Experts are reviewing a proposed set of CSC chamber positions • X/Y from laser alignment, endpoints based on disk survey • Z based on disk survey • Some inconsistencies in the Z-sensor array • RotX based on laser alignment (chamber tilt from disk bulge) • No handle on RotY • RotZ based on disk survey
James N. Bellinger 4 July 2010 Projects for CSC • Transfer line validation • Apparent disagreement w/ Barrel MAB positions • Z-sensor validation • Apparent disagreement w/ Link MAB Z positions • Step through procedure to automate coordination of fitting data from 7-June • Target end of July for first pass • Unlikely to get enough tracks for tracking tests by then
