keyword=Left Q2 Ramp Problem
Left Q2 would not cycle above 1570 amps. Fault indications on GUI were "Quench" and "Interlock". After reviewing the stip charts, we found no evidence of an actual quench. Hall C is currently cooling their target, we believe it is effecting our lead flows. Right Q3, and Left Q3 tripped with the same indications. I attempted to cycle left Q2 with the same results. I increased the lead flow by 5 percent, and Q2 cycled normally. Both Q3's were reset remotely, and cycled normally. All magnets are operational at this time. It is likely we will see more magnet trips while the hall C target cooldown continues.
