Injector Shift

Beam was running smooth until we started getting immediate injector BLM trips. We put in the ILD and found that there was a large position change in the 0R region. Which led us to believe that energy had shifted. But further investigation found less noticeable shifts further upstream. I'm wondering if this is another discharge event. That being said, our normal injector discharge indicator, IPM0I05, only had a minor change and this event lacked the slow change in injector orbit that would normally occur before the discharge.

While we were investigating, a few cavities in 0L04 tripped RF.
