keyword=initial looks at pulsed-beam dataFrom run 4222, after Brad and Bogdan setup the discriminator for the liquid scintillator neutron detector (present for testing purposes), and called d3 here. The first figure shows the pulsed beam structure in accidentals between the d3 and BB's scintillator plane. This can be used to help determine path-length corrections in BB, as well as improve the timing calibration of BB (assuming we get tracks with these events). The second figure shows the resolution of d3 is at the 1ns level (FWHM) when compared against the RF-phase. This data quality is good enough to use for calibration. From 116k events, 50k have good signals from d3.
