keyword=Septum Tripped again
When beam came back after beam studies, the BPMB Y position was off by -2 mm. I noticed by looking at the earlier trip that when the Bullseye Scan was started at -2 mm in Y that the Septum slowly started to heat up and the ion chambers jumped from about 400 Rads/hour to 1400 Rads/hour, see Figure 2. Eventually the Septum coil temperatures reached 9 K causing the quench of the lower coil. By the time I realized that the Bullseye scan at -2 mm caused the Septum heating, the Septum had already tripped and the lower coil quenched again.
