    keyword=Bigbite proton TOF vs momentum

    For your amusement, here is a table of proton time of flight in BigBite. These times, in ns, assume a 3 meter flight path.

    One implication of this is that we need to remove time from the TDC starts in BigBite because the gate will be arriving too late when we are looking at higher momentum protons (e.g. 600 MeV/c). Olivier and I will go into the hall at 5PM to adjust timing of the BigBite gates.
