A Distributed Frequency RF Scheme for Capture of Muons

Bob Palmer [1] has proposed a scheme for the capture of muons using only medium frequency RF. It comprises of a decay and drift area, where the correlation between momentum and time is formed. The beam is then bunched using RF (at a frequency near to 200 MHz) where each bunch is formed at a different average momentum. By beating two close frequencies the average momentum of each bunch can be corrected. The clear advantage of such a scheme is that it uses standard medium frequency RF with which the accelerator community has much experience and high gradients have been obtained. However, it will be shown that the number of muons is not (so far) interesting.
