[Sphenix-magnet-l] Gas or air release every 10-15 seconds ?

Dear Roberto and Chintan and all,

I don't go to 1008-IR as often as I used to a month ago.

Today, as I told you over the phone, I heard the noise from the upper platform every 10-15 seconds or so. After our phone call, I walked up the platform and chased the noise to this piece of Cryo equipment. I am sure it's this because I felt the release of gas/air with my hand, in addition to the noise. Somebody wrote "leaking" in red.

I don't remember hearing this during magnet mapping. Is this OK ? Something broken ?

We are not doing any cooling any more. Why is it doing this ?

( Technicians told me that it has been like that for some time. It may stop in the morning and then will happen again in the evening. )

Kin
