Abstract:
Muon beamlines such as the one being designed for the MECO experiment
will provide a large increase in muon stopping rates, allowing for
possible large increases in sensitivity to $\meg$. As higher-power
proton-drivers become available, even higher rates will become possible.

We have analyzed the capabilities of a detector for $\meg$ using
pixel detectors to track the positron, and a conversion pair from
the photon. We find that an initial detector with a beamline
comparable to MECO and 10\% of the coverage of the MEGA experiment
can already be competitive with experiments currently under
construction with a modest amount of live-time. By increasing the
coverage and running longer, it should be possible to go further.

We have found that the accidental backgrounds depend strongly on the
thickness of the photon converter, providing a way to make continued
major progress as improved pixel detectors and more intense muon
sources become available.
