InfoThere are three runs (3512-3514, 5M events) taken at 60 V, threshold=0.937 V, VNC1-3=30, that in principle could be added to the bias scan, if we confirm the VNC settings for above list.

Question would we use runs 3393 - 3405 ? These are a set of runs taken at 0, 5 and 80 V bias, but with a threshold of 0.945 V.

  • 3394- 3396: Vbias = 5 V, 5M events
  • 3393, 3397, 3398: Vbias = 0 V, 5M events
  • 3399 - 3405: Vbias = 80 V, 14M events <==== alignment studies ??
