The 3MW of used proton
beam
•One awkward
issue is that most optimisation studies
have shown a small angle (~0.1rad) is best
for pion production
•But in my
optimisations the optimal angle seems to be
near zero!
•This could be
because the other studies have looked
at the pion yield closer to the target and
not downstream.
•Tilting the rod
could give a higher initial yield but
with a larger emittance
