<pre wrap="">All,
With the existing loads on ESR and the plant at full discharge pressure, the dewar was filled ~0.23%/hr, or less than 1g/s of additional capacity.
The test was performed between 10pm 11/13 through 10am 11/14.
Regarding a full-load ESR test:
The CHL plants are stable and cryo would like to begin the process of scheduling a test that will include all expected loads for the Fall 2017 run. This would require that all magnets be cold, energized, elevated lead flows, and a cold Hall C target with additional load to supplement the missing Hall A target loads.
Can this be scheduled for the end of this week or beginning of next?
