[Prex] [New Logentry] Increased ramp rate

Beam looks stable at 150 muA and Compton rates decent 5.5-6.5 kHz. Called MCC and they said they steered up the injector and were able to run the compression at 1L04 at 1 deg above max compression which apparently is where Comptonia likes it. This was previously not possible because this setup causes a tail on the C beam which was causing BLM trips in the injector at 0R08. The steering involved moving the beam away from this BLM which then allowed the gang phase to be adjusted to higher compression. So we have decided to still run though the chicane. If we can run stably like this it would be awesome. Asked MCC to increase the ramp rate to 40 muA/s. They said they had previously run into overshoot which tripped the beam at that rate but they will try to increase it as high as they can stably. Keeping our fingers crossed.
