Hi, Carl,
The Cryo group opened the valve ~ 11 am this morning. As shown in the plot attached, the sharp cooldown dropped ended around 15:15 pm at about 5.2 K
and then continued to drop slowly. Now, for MT01, it's dropping to ~4.9 K :-)
I think the Magnet will be at 5 K or so for almost ~19 hours by 10 am tomorrow, good enough for hipot :-)
Kin
