Abstract

The Fermilab Muon g-2 experiment will measure the anomalous magnetic moment of the muon to a precision goal of 140 parts per billion, which is a factor of four improvement over the previous E821 measurement at Brookhaven. Both of these measurements are made by an analysis of the modulation of the decay rate of the higher-energy positrons from the (anti-)muon decays recorded by 24 calorimeters and three straw tracking detectors. The straw tracking detectors will be used to cross-calibrate the calorimeter, identify pileup and muons lost from the storage region, and to measure the beam-profile. Quality control in the straw tracking system is of particular importance, as the uncertainty in measurements taken by the tracking system will be determined by the quality of construction of the trackers. A dedicated quality-control system consisting of a radioactive source mounted on a movable stage using a silicon photomultiplier detector has been designed, constructed, and is in use to measure important parameters of the straw trackers. Currently measurements of the gain and plateau region have been successful, but work is ongoing in measuring the wire and straw positions of the tracker.
