In the last four years, several new techniques to cool muon beams have been invented and are under development supported by DOE Small Business Innovation Research grants. A short summary of these grants and 5 new proposals related to muon beams follows.

In February, Muons, Inc. and the Fermilab TD sponsored the first annual low-emittance muon collider workshop at Fermilab (~65 participants). There is growing excitement about MC feasibility and synergy with the ILC.
