Description

This mini-workshop will bring together researchers working on the re-acceleration of very low-energy muons. We will discuss the efforts in Japan, in particular at KEK/J-PARC, and in Switzerland to develop techniques for accelerating eV–keV energy muons to the MeV scale. The workshop will highlight the different approaches, current experimental progress, and the challenges involved.
