- We've had issues with the CCAL HV crate. The problem is with the control module in the crate directly. We replaced the crate, but now the voltages can't be seen in the EPICS and we are running almost blind with regards to CCAL voltages (can still check scalers as a basic check though).

- We decided against increasing the beam current because the statistical improvement is not enough to justify any potential risks. Also, increasing current would require us to turn off the CDC.
