Abstract The Muon g -2 Experiment at Fermilab uses a gaseous straw tracking detector to make detailed measurements of the stored muon beam profile, which are essential for experiment achieve its uncertainty goals. Positrons from decays spiral inward and pass through before striking an electromagnetic calorimeter. is therefore located inside vacuum chamber in region where magnetic field large non-uniform. As such, must have low leak rate maintain high-quality vacuum, be non-magnetic so as not...
In order for the analysis of data from tracking detector to reduce systematic uncertainty on aμ measurement and improve sensitivity a muon electric dipole moment, internal position modules must be known high level precision. Track-based alignment was implemented with Run-1 using Millepede-II framework. An overview methods, as well verification simulation, will given. A significant improvement in mean p-value distribution fraction reconstructed tracks after achieved. comparison accuracy...
The $g-2$ experiment successfully completed its second data taking period (Run-2) between March and July 2019, with the analysis of Run-1 Run-2 currently proceeding. final goal is to determine muon magnetic anomaly, $a_μ=\frac{g-2}{2}$, a precision 140 ppb. Essential reducing systematic uncertainty on $a_μ$ through measurements beam profile are in-vacuum straw tracking detectors. A crucial prerequisite obtaining accurate distributions internal alignment trackers, which described here, along...
The Fermilab Muon $g-2$ experiment is currently preparing for its fourth data-taking period (Run-4). experiment-wide effort on the analysis of Run-1 data nearing completion, with announcement first result expected in coming months. final goal to determine muon magnetic anomaly a precision 140 ppb. This level will provide indirect evidence new physics, if central value agrees previously-measured anomaly. Essential reducing systematic uncertainty, through measurements beam profile, are...
