[SBS_sim] SBS-Tracker: New production with magnetic field

[Bogdan Wojtsekhowski]

Hi Evaristo,

I don't understand what is the background that was used.
I need the accurate information about the background.
Why are we using background for 0 T field?

> The electrons and gammas background are from production g17 (with 0 T
