13:00 Carsten called. Lead Glass counters (Scope ESA brown trace) was left at 900V and 10mV/div scope display last night in anticipation of primary beam. He raised the HV (to 2K?) and scope back 50mv/div. Signal size 50-100 mV for the ~50 particles per shot. He moved the counter slightly to verify signal went away so it looked like crudely beam doesn't have duffused tail. End of the night data-taking:
Select data worth looking at:
~3:00 PM Run 346. A long run with the LBNL cosmic telescope and full MIMOSA. Su Dong, Zijun, and Sanha found out from this run that the second FEI4B module of the LBNL cosmic telescope wasn't outputting anything. This module was almost completely masked out during the fasttune process. Sanha tried re-calibrating and re-tuning the module for a while, but could not fix it. (Su Dong and Zijun checked for any hardware issues later in the afternoon/evening, but couldn't fix it either.)
~3:50 PM Run 350. Timon got a first successful run with one RD53A module.
from 7:45 PM to 8:25 PM Run 400. A long run with one RD 53A RD53A module and full MIMOSA (full 10k events). The beam did not cover the entire RD53A sensor area, so Ke and Sanha tried tuning the fine position to move the module around
