Re: [AMMRL] Ice noticed on Nitrogen equilibration exhaust line.

to find „closure“ on this - did you check if all exhaust ports are indeed still open…?

I forgot to mention that in the long term such ice (and/or dripping moisture) buildup can lead to increased corrosion on the contact surface between (aluminium) bottom plate and (stainless steel) upper body, around the large circumference of the main vacuum O-ring when water finds its way into the gap at the bottom flange. A telltale is the buildup of streaks of water stains running down the magnet below the nitrogen turrets. Such corrosion can eventually lead to vacuum loss, increased helium/nitrogen consumption and even eventual quench…

Cheers
