The prototype runs at CMU were made with the prototype sitting along the top of one scintillator. The scintillator is only slightly larger than the prototype.
Run 2016 at JLab was a cosmics run with the BCAL trigger.
The CDC run at CMU used two scintillators in coincidence, the scintillators were above and below the CDC, separated by approx 2m, and are 9" wide. The cosmic rays would have been much closer to vertical than for the prototype and JLab measurements.
CDC at CMU had MPV at ~190 for 2110V, 50/50 Ar/CO2. CDC wire is 20um, prototype wire is 18um (7 mil), and prototype straw radius is also slightly different.
