<p>We have stabilized our flow control at 7g/s. The dewar at ESR is no longer dropping level and is filling slowly. </p>
<p>The Torus coils average temp is 78K and are currently cooling at 4.2K/hr (average over the past 30 minutes) and this rate is presently dropping. </p>
<p>The Solenoid coils average coil tempeature is 91.1K and over the past 30 minutes has been cooling at 1.2K per hour which we expect should stay roughly constant for quite a while</p>
<p>Denny, Sandesh and I will monitor the system over the weekend. We will probably stay in warm until Monday morning but will keep in touch with our buddies in cryo if we or they need to change plans.</p>
