Abstract
At PSI we are investigating the technique of decelerating an existing very intense secondary beam of surfaceμ + (∼4 MeV) to an energy of ∼10 eV using appropriate moderators. Theseμ + can then be used as a source of a tertiary beam of low energy muons with tunable kinetic energy between ∼10 eV and ∼10 keV.
With a 1000 A layer of solid Argon deposited on an Al substrate we obtain a moderation efficiency (with respect to the number of incoming surfaceμ +) of the order of 10−4.
Results of our investigations and the present status of the project are presented together with future plans and possibilities.
