Access code:
  • Lab Update
    • Leak detector below 10^-6 mbar during weekend. Cryocleaning ongoing, below ~100 mbar in contaminant level. Need a couple of more cycles.
    • Leak checking on edges on IVC seals on IVC fine. Raised Main Bath.
    • Leak checking again shows signal more than 10^-6 mbarL/s. This was seen earlier and come from the top indium seal which seem to be needed tightening with every cooldown now.
    • Slightly lowered MB and tightened the screws further. Not much movement, only can hear metal cracking sounds.
    • Raised MB again and this time leak signal was low.
    • As soon as I start pumping out the He gas from MB, leak signal jumps very high. Not sure the reason.
    • This might be other place or that seal in not holding up for long time?
