BCAL SiPM baseline current

[Alexander Somov <somov@jlab.org>]

Hello all,

Here are some MC estimates of the number of photons at
the ends of the BCAL bars induced  by hadronic interactions
and EM background (and corresponding SiPM baseline current)

http://www.jlab.org/~somov/bcal_cur.ppt

Note, in the simulation the number of photons produced per
1 MeV energy deposited in the scintillator (per each bar side)
is 75. This number is taken from  the prototype cosmics tests,
GX-doc 1069. Therefore, 1 GeV photon passing through the middle
of the bar produces 120 MeV * 75 * exp(-2/3) ~4 600 photons at
each bar end.

Cheers,
        Sascha
