4. IMPORTANT ANNOUNCEMENT ! ! !
Hi all, I spoke to Dean regarding our shifts this week: (i) There was a water failure on the Linac yesterday so the machine is still not on. Tonight's shift is at risk. (ii) Dean couldn't find shift cover for Saturday so we will be limited to 1V on Saturday. He will cover the shift on Friday so we can get up to 4 V for the high intensity study on Friday. We should plan accordingly. I will probably see you later so we can talk then. Regards, Chris

37. Hi Ken I’ ve come up with a set of orbit changes in the ring that could (if they work) steer the beam away from the target  at < 8 ms by up to 10 mm. Then steer to the target from 8-9 ms by up to 10 mm and holding steady from 9-10 ms.  This should hopefully give you a more beneficial spill time, deeper dip potential and save us some unnecessary beam loss.  I will try to produce the orbits at some point during startup if there is time and then we could possibly have a go for real if your in agreement.
