— Yuri revisited alignment based on the studies shown by Rongrong before the holidays

— was some T0 change that was not accounted for and exploring alignment parameters

— would like to have alignment done for all of past 5 years

— Tommy working on TPC RS

— comparing DAQ 5k and DAQ 1000

== AOB

— Gene looking at field cages shorts from past couple years

— spotted a sharp jump of ~15 volts in central membrane voltage 

— decayed down by ~5 volts over a few days

— all 4 field cage currents showed a sharp rise at the same time though the decay profile was different
