DESCRIPTION:Speakers: David Hitlin (California Institute of Technology)\nW
 e present the status of Mu2e experiment for the search of coherent\, neutr
 ino-less conversion of muons into electrons in the field of a nucleus to a
  few parts in 10⁻¹⁷\, a sensitivity improvement of a factor of 10⁴ 
 over existing limits. The Mu2e experiment will be hosted by Fermilab at a 
 new muon campus. It will use a complex of solenoids to collect and transpo
 rt the muons\, produced when the 8 GeV pulsed proton beam hits the tungste
 n production target. The last solenoid in the complex will allow for the m
 easurement of the momentum of the electrons produced by the muons trapped 
 into the muon stopping targets. To this goal\, Mu2e will adopt a challengi
 ng detector system. We present a detailed description and the expected per
 formance. The central part of the detector is a low-mass straw tube tracke
 r immersed in a 1 Tesla uniform magnetic field and placed in vacuum (10⁻
 ⁴ torr) to efficiently identify 105 MeV/c electrons\, with a resolution 
 of the order of 100 KeV/c\, and to reject a large amount of background hit
 s (average hit rate of ~15 kHz/cm²) within a high radiation environment (
 peak hit rate of ~3 MHz/cm²). A BaF₂ crystal calorimeter\, downstream o
 f the tracker\, will provide particle ID\, to further reduce backgrounds\,
  energy and time measurements. The large detector area will be extensively
  covered by multi-layer scintillation counters to reject\, at the level of
  10⁻⁴\, cosmic rays that could mimic signal tracks.\n\nhttps://indico.
