Description
The FNAL E989 experiment is seeking to measure the anomalous magnetic
moment ($a_\mu$) of the muon to a precision (0.14 ppm): four times better
than previously achieved and to extend the sensitivity to a muon
electric dipole moment (EDM) by two orders of magnitude. The
experiment will re-use the E821 BNL storage ring but will be upgraded
with new detectors, kicker magnets, collimators and improved
quadrupoles and field monitoring. The detector system comprises 24
lead-fluoride calorimeters and 3 straw tracker stations. The straw
trackers are essential in measuring the beam profile, identifying
lost-muons and pile-up and provide the means to probe the muon
EDM. In this talk the design of the E989 straw trackers will be
described and recent results of their performance from test-beams will
be shown highlighting how the trackers will improve the systematic
error determination in the $a_\mu$ measurement.
