    keyword=Still target alarm under 100uA, decide to run under 90uA tonight

    We are running fine under 90uA beam. However, once it goes up to 100uA the target alarmed which might be caused by the temperature went out of range. We suspect that it is the PID cannot respond quickly enough when the current changes sharply under 100uA. The target operator will give a detailed log about what we did soon.
