Dear Peter & Tom,

thanks really a lot for your info, but I think I was not sufficiently clear. I have a scintillator detector (1m^3) that should be able to discriminate a muon with a certain momentum value (200 MeV/c) from the electron produced from the muon decay. I don't know if the muon are polarized, but I guess no. Before my detector there are a lot of detectors and dipoles/quadrupoles. But I know the muon distribution at level of my detector and the fraction muon/electron.

So my idea was to create an electron beam from the muon one. 400 m was a good compromise between the quantity of decayed muons (larger space, larger electron number @ detector) and the electron divergence (larger space, lower electron number @ detector).

As stated also by Tom, just a fraction of the muon decays in time to allow electrons to hit the detector. So, for time saving, I would like to create an electron beam with the good features (energy and angles). The only two ways I see are: 1) electron gun with good energy (from the V-A theory) and good angles; 2) electron gun from muon decay (as I want) forcing the muon decay in a few cm.

So, what's the best solution? 1) is it possible to force the muon decay in a few cm (in vacuum or air, of course!) 2) if not, is it possible to create the electron gun with good features? Do you know how to create it?

Thanks really a lot again!

Davide
