chopper 1Y troubleshooting
started troubleshooting the chopper 1Y chassis after the system couldn't regulate the phase and amplitude earlier today
we removed 1 dB pad to have some headroom in the drive signal. This didn't last long as we had to come back after couple of hours with the same issue

Injector status
1. Around 1440 chopper 1Y started to show instability (fig. 1)
2. After Rama and company made it work we started to recover the injector. But chopper 1Y was not stable.
Around 1830 it was getting worse. Rama and company took over to work on it. Rama said that the Buncher may have power issues too. He is going to take a look at it.
3. Having been here since 7am, I am getting tired. Reza will take over to restore the injector after chopper is fixed.
