Sep 22 2017 JLEIC Ion Integration Meeting
pCDR Planning
- Presented pCDR planning slides at Sep 13-15 AAC meeting
- Bob McKeown also showed the current JLEIC strategy and organization
- Todd and Rik are leading documentation and pCDR efforts
- The pCDR is not just a technical design report
- A portion of the pCDR is consistent technical design of all accelerator segments
- The most current (very drafty) pCDR outline is located here (Dropbox link)
Near Term Action Items
- By Tue Oct 3
- Identify and prioritize remaining work needed on accelerator segments to deliver relevant consistent pCDR draft sections by April/May 2018
- Will review and collate at next integration/pCDR meeting (Fri Oct 6)
- By Tue Oct 31
- Draft initial machine segment documentation
- Includes upload of relevant (even draft) best present accelerator segment lattice files to svn
- Document should be consistent with, and include references to, svn lattice file version(s)
- Zip file of "template" (Todd's Booster tech note) located here
- Iterations, if needed, at Fri Oct 20 integration/pCDR meeting
