Access code:
  • Lab Update - Run 79 ongoing
    • Found new shorts on Cable 2 at random phonon and SQUID/Feedback lines. Not seen during cooldown.
    • Tried Switching between DCRCs to see if we can keep Tower temperature lower, but didn't help.
    • Used diverter board to disconnect all lines except pD(Side2pE) to read that channel only. Still temp in 72 mK, no pulses.
    • While trying to get data with other two cables, found that as soon as we connect the time sync between DCRC, QET bias change doesn't respond. After trying different configurations of Master/Slave, found one when all 3 DCRCs are synced.
    • Anthony needs DCRC4 as soon as possible to update software configurations even for this run's neutron study, so I tried using an old DCRC(DCRC5) instead of DCRC4 to use the time sync and it is working that way.
    • Plan: Take data with Cable 1 and 3 at different y-position. Try moving X arm as well.
    • Warm up and check that SQUET.
