h2. SSU-M1 Instability 2016-10-22

To study the instability of SSU-M1, I tested the theory that there is a resonance in the circuit around 6A in SSU-M1, or about 3V on the PSU output. The history of the ramp this morning is shown here:

Or, as seen from the QPS, where the beginning of the plot is at 6A in the M1 coil.
