None measure position, momentum and energy of a proton...

Hello, I am a bit lost !!! I am actually creating protons and measuring their contribution in a sensitive detector (at about 12 meters away...) By definition my source is quite wide and only a few percent of the proton interacts with the sensitive detector...

So i came with the idea of using an "intermediary source" placed at about 9 meters from the initial one ... For that purpose i plan to measure the position, the momentum and the energy of each protons going through a sensitive volume (9 meters away from initial source) and to use these results to create the new source ...

I am confused with the kind of detector to chose and how to implement it...

For a better description of my problem, here is a "graphical explanation" of what i want to do:

 Initial Source ----------------------------------------------->> Water phantom  (only 1% of protons reach the target)

 Initial Source ------------------------------OO Sensitive detector

                         Intermediary Source  ----------------->> Water phantom (better stats : 20-40% protons reach target)

I hope i made it quite clear !!!

Regards, Frédéric.
