Abstract

The Muon g-2 experiment at Fermi National Accelerator Laboratory is structured to study the physical property of a muon particle. The first experiment, however, found 3 sigma of standard deviation different from its prediction. Therefore, the second experiment will try to redesign the muon tracker in order to achieve higher resolution. When muons precess under a specific magnetic field within the storage ring, they will be captured by series of muon trackers, then the measurement data will be used to calculate and compare with the theoretical prediction. Since argon-ethane gas will be filled inside muon tracker, one of the purposes is to make sure the flow inside muon tracker is evenly distributed. Otherwise, resolution will be compromised. What's more, muon trackers will contain electronic components inside in order to record muon data. At the same time, electronic components generate heat inside muon trackers. However, due to tracker dimension confinement, traditional cooling method such as gas cooling or water cooling become hard to achieve. A new feature design is needed to solve this nontrivial thermal problem. The limitation space inside muon trackers actually also lead to a new separate system set up. For the flow and thermal problem, simulations were run using ANSYS to validate conceptual design. Subsequent geometric and thermal analysis was performed for further model optimization. In the end, a refined muon tracker design with proper cooling capacity was confirmed.
