Muon to electron conversion: The COMET and Mu2e experiments
  I describe the new generation of muon-to-electron conversion experiments, COMET and Mu2e, being constructed to make use of new high power pulsed muon beams a J-PARC and Fermilab respectively. A brief overview of the physics explored by the muon to electron conversion is given, followed by a description of the experimental challenges and resulting features common to the new experiments. The differences in approach between Mu2e and COMET are then highlighted, and the current schedules given.
