Hall B ran nicely over the weekend. Today and tomorrow we will be testing the range of the Torus superconducting level probe. During previous runs we had to run on the differential pressure level probe (LL8120DP) at 72% setpoing this caused the SC probe to to read 100%. We did this to keep the magnet stable. Over the SAD we raised the SC probe and this seems to have worked nicely and over the weekend we ran with the SC probe as the input at 80% with the DP probe tracking around 66%. I am going through a range of setpoints to see where looks best for stable Torus Ops.

On the Solenoid we will be emptying the Magnet reservoir (which always returns warm) to allow installation of relief valve heaters. These heater will be operated after a fast dump to help seal the relief valve. Minimal impact to the ESR or recovery system is expected.
