Hi Sasha,

 

Thanks for the quick comments.

Yes, the membrane is 0.125” thick which is about 3.17 mm .

Thanks for pointing out about Y efficiency. I should add that number on slide #15. Basically we disn’t really see any significant change in the Y efficiency. Overall the Gaussian fraction to input upsilons in Geant4 is about 16%

Thanks,

-Sourav

hi Sourav,

i didn't know about the thick membrane. is it 3mm thick?

looks fine, however, you only discuss the Y-line shape modification, what about Y efficiency reduction? is there a number?
