For the Injector Upgrade I have rearranged several bpms on IOCSE11 and IOCINSE4. This was done mainly because many of the front end injector bpms have new names. I wanted the bpms on the ioc's to try and fall in order. I have been rewiring the electronic racks upstairs for this and also entered all the changes (bpm names, new channel assignments .etc.) into the Injector upgrade workspace of CED. Yesterday the Injector upgrade workspace was rolled over to the Ops Workspace and now all my bpm changes are Live on IOCSE11 and IOCINSE4.
Day #28, Week 6 Day 3, Wrap-Up:
* New Wien HV and interlock cables staged to be pulled
from new rack IN01B01; HV controls work continues
* Plan formulated for Gun2 table move (staying in tunnel)
and Y-Chamber+Gun3 removal, to occur tomorrow (10/29)
early morning (prior to 8AM meeting). Please keep away
from Injector tunnel during this work.
* CED merged such that AIPINJ Phase I upgrades (gun to
chopper) are now reflected in Ops workspace
Other Injector SAD Work --
* Viewer upgrades -- CAMAC to VME, cameras --
* PSS Upgrade continues. 3855899?
The CED InjUpgrade workspace has been merged into the OPS workspace, which means that the CED OPS workspace reflects the to-be-installed upgraded beamline up to MFA0I03 (just upstream of the choppers). Any CED element property changes should be merged into the OPS workspace now.
Revisit the ATLis (21440) Risk Classification (pre-mitigation) found in the STATUS section after reviewing the (attached) 2020 Standard Hazard Analysis ... a number of "YES" are identified in the ATLis Hazard Identification Worksheet (below) and the 2020 Standard Hazard Analysis indicate the pre mitigation risk code is "3" for most.
My first attempt at a golden orbit using the two new apertures, A5 and A6. Raster is ON. THere appears to be excellent transmission through A5 2mm hole, no readable interception (probably need to use decarad or the silicon PMTs to record loss).
To find the golden orbit, we will tweak steering magnets 904A H&V, move the aperture A6 if necessary, and send beam to dump, monitor beam position while IBC magnets are varied, more later.
Beam restored very easily today at 9.7 MeV/c. We just left the laser setting the way Yan left things last night and ran CW beam to all viewers, without problems YAG and chromox. Fiber amp setting ~ 350 mA (compared to 1900 mA).
Based on Yan's comment from last night, and we put the beam in MeV spectrometer and phased up the buncher, and booster. Then quad centered thoroughly.
We looked at the beam on ITVM905 and noticed vertical motion indicative of energy jitter. So Andy wondered if the 9.5 MeV/c beam would be more stable and it's the momentum that Charles simulated.
