On 06 Mar 2023 we started the Liquefier A after cleaning up the Dewar A level sensors using the procedure (docdb). According to the procedure, the bottom tube did not vent gHe on 04 Mar 2023 when the cold head temperatures are slightly above 240 K. So, we had to wait until all the cold heads are above 272K.

Since then (03/06/2023), Dewar A wasn't producing liquid until the 03/19/2023 afternoon. Below is the log of things that we did.

Around 11:26am on 03/12/2023
