[Halld-tagger] range of electrons in Silicon

[Richard Jones]

Gentlemen,

I have attached the dE/dx curve for electrons.  When I read this curve off during the meeting, I was off by a factor of 10.  Actually, the range of 1 MeV electrons in Si is above 500 microns, closer to 1 mm.

At the link below is the log_base_10 of the recoil electron kinetic energy (y axis) vs lab theta.
