<p>Hall B is still taking 3g/s of warm (4atm) helium.<br />
The Torus and Solenoid are warming at 0.01K/hr (as you can see on their helium screens)<br />
Torus is at 88.6K, Solenoid at 87.5K and Buffer Dewar has 101K in and 196Kout</p>
<p>I'm shutting PV8563C for the work on the ESR today. I may reopen it after the work depending how much the Magnets rise in temperature over the day.</p>
