Tracking

• 

  Slide illustrating the requirement on track resolution for Mu2e-II compared with Mu2e. Note that the resolution has contributions from several sources. The blue dashed curve on each plot indicates the electron spectrum from muon decays in orbit (DIOs). The red curves show the conversion electron spectrum for the values of [math]\displaystyle{ R_{\mu e} }[/math] indicated in the legends.

Cosmic Ray Veto

The Mu2e-II Cosmic Ray Veto will need to cope with roughly a factor 3 higher instantaneous rates from accelerator compared with Mu2e as well as a factor of three higher live time (i.e., cosmic rays), because of the higher duty factor for Mu2e-II compared with Mu2e.
