CCR tuned beam most of the night for new Target Holding field.
Ran ABS Hydrogen.
First run at 9:45pm. Injection takes slightly longer, delivers 120mA at
an initial lifetime of 11, which recovers quickly to over 20min at 90mA,
23min at 83mA etc.
Took several runs.
When the voltages move from stby to oper, both left and right Lead glass
(or at least whatever this is actually hooked up to) TOF and cerenkov turn
off. We pressed the ON button.
Target Cell temperature was high. The value on dblast14 was at 115K. The
actual Cell sensor was at 110K. Put software on CONTROL, lowered setpoint
to 80K. In 90min the dblast14 value dropped to 100K. Moved setpoint back
to 90K.
Runs taken 973, 975, 976, 977, 978. Runs crunched.
