  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.
