keyword=brief HIHI in loop1 temps.
The temperatures on loop 1, loop1/temperatures1 had a few minutes excursion into the HIHI region, T>23K. I tried opening the JT valve on loop1 to 38.5. There was no evident response on the JT gui, but the temperatures went back into the safe range.
It is not clear to me why the excursion occurred. There did not seem to be a beam spike.
