Abstract

The mission of the Fermilab Mu2e experiment is to detect the conversion of muons into electrons in the field of a nucleus. This conversion process is known as Charged Lepton Flavor Violation (CLFV) in particle physics. The Mu2e sensitivity is expected to be four orders of magnitude beyond the SINDRUM II experiment at the Paul Scherrer Institute. To meet this expectation, the experiment requires a low energy muon beam and a high precision detector. The Fermilab accelerator complex will be utilized to generate a proton beam in which a production solenoid (PS) will receive to produce the desired muon beam. The beam will then travel through the transport solenoids (TS) to a detector solenoid (DS). The sensitive measurement components such as the proton absorber and calorimeter, simply called the DS train, rest on rails within the detector solenoid. During installation of the DS train, component positions must meet a +/-2 mm tolerance. To ensure this goal, DS train components will undergo a new design iteration and will be evaluated through finite element analysis (FEA). Axial couplers used to connect each component on the DS train, will be designed and analyzed to prevent buckling and minimize deflection from the 2000 lb compressive load. A support stand for the instrumentation feed-through bulkhead (IFB) will be modified to facilitate the expected installation forces in reference to the ASME Division II guidelines for pressure vessels. The DS train installation process will need to be reviewed to prevent failures. This includes analyzing the pallet lifter chosen to extract the external stands the DS train rests on. Analysis is necessary to confirm that the trench grating that is built into the floor below the DS train will not bend significantly under the loading from the extraction process. Critical review of the components and installation of the beamline system is vital to the success of Mu2e.
