~800 kW total (75uA), but with BLM trips - 70uA stable. Hall C is anxious to take beam, so handing over to them. We can revisit BLM trips etc. and try to push again on next RF recovery day, or at a time set by the PD. [Using the 3C12 energy excursion monitor Tom/Jayendrika configured, smartRAT, and other such tools...]
