keyword=Increase current to 50 uA for (155,0) kin.Run 1723, I_beam=25uA, 1st picture
The fisrt plot is tc_cor without any cuts. The second plot is tc_cor with the proton and vertex difference cut abs(e.reactz-h.reactz)<0.03. The third plot is the tc_cor with the same cuts of the second plus the missing mass cut 100
Adam decided we should increase the current to 50 uA to get more interested
coincidence events.
Run 1733, I_beam = 50uA, second picture
with the same proton , vertex and missing mass cuts,
the Signal to Noise ratio is 4:1.
It seems we can just keep taking data at this high current.
