"This is one of the most fascinating measurements I ever wanted to be part of. Using completely different techniques from "normal" collider analyses we can probe physics in a new and super sensitive manner.

 This experiment is the latest in a line of famous muon experiments to measure its spin. The spin is predicted by the Standard Model to be very close to 2 with a precision of  100 parts per billion. At the beginning of this century a measurement at Brookhaven found a value that was only 1% likely to be compatible with the predicted value. At FNAL we needed to pin this down.  

 Together with UCL, we designed and built the new tracker stations that would yield a new handle on the systematic errors of the muon magnetic moment.
