keyword=Target: should keep HighPower heater to non-zeroNote to TO: please always keep HPheater power to be non-zero with full beam current. When it is zero it can not regulate, and target temperature will not be stable. I increased coolant flow from 24.5 g/s to ~25.2 g/s (It can slightly exceed 25 g/s, try to not exceed 25.5g/s) to have non-zero HP heater. It also helps to not have large temperature drop when beam trips.
