Hi Krister Etal,
On the buffer dewar we also use a temperature signal to help to keep the
line cold. I do not know if the IBC has a temperature signal in the flow
path of the 4k pot that might be used. but if it does we can set up a
cascading PID to keep the supply valve minimum position high enough to
assure the u-tube stays cold.
I'm happy to meet with you, Andy and Chris to implement this feature if
there is a signal that can be used.
