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
pCDR Accelerator Segment Needs
- Polarized Ion Source (Amy)
- Heavy Ion Source (Amy)
- Ion RFQs/Linac (Brahim)
- Linac to Booster Transfer Line (?)
- Ion Booster (Ed/Todd)
- Booster to Collider Transfer Line (?)
- Ion Collider Ring (Vasiliy)
- CEBAF (Jiquan)
- CEBAF to Collider Transfer Line (Yves)
- Electron Collider Ring (Fanglei)
- Low Energy Cooler (Yuhong)
- High Energy Cooler (Steve)
pCDR Accelerator Segment items from Engineering (Tim)
- Ion Sources and Linac
- Status: Limited to basic element list and cost information from Jan, 2015. Basic origin defined.
- Would like to get models of elements to develop basic CAD layout in NX.
- Space and tunnel/vault sizing
- Summarize power requirements and cooling needs – parameterization.
- Linac to Booster Transfer Line
- Status: Undefined.
- Get lattice file
- Develop layout
- Define start point and connection point to Ion Booster Ring
- Size and layout of tunnel to connect Ion LINAC tunnel/vault to Ion Booster Tunnel
- Diagnostics???
- Other parameterization???
- Ion Booster
- Status: Origin defined. Based on TAMU 1.2m model dipole.
- Development of tunnel
- Transition transfer lines in and out
- Kicker
- Diagnostics???
- Abort/dump system???
- Other parameterization???
- Booster to Collider Transfer Line
- Undefined.
- Ion Collider Ring
- Status: Origin defined – at IP. Basic tunnel layout complete – need to update with overall SF magnet model.
- Updated lattice file and layout – look at % filled.
- Resize tunnel to accommodate RF Cavity spacing from floor/wall
- Feasibility / sizing of SF magnets (11.4m model of dual 4m dipole/quad combo in a single cryostat)
- Diagnostics???
- Abort/dump system???
- Other parameterization???
- RF HPA system basic model/layout – basic assessment of routing waveguides from surface to tunnel
- CEBAF
- Status: Origin of CEBAF is the Origin of all JLEIC Site Layout
- Need to assess CEBAF Reliability/Availability and its impact on JLEIC Reliability/Availability
- Need definition of operational scenario, time to fill ECR, top off rate, etc.
- CEBAF to Collider Transfer Line
- Status: Very old and outdated lattice file from Yves based on PEP-II LER Dipoles – note that it does not line up with position of the Electron Collider Ring as it sits now
- Get updated lattice file
- Develop layout
- Based off CEBAF Origin – needs start point and connection point to Electron Collider Ring – how does it enter Electron Collider Ring (ideally from above, but latest thought is from below so as not to affect Electron Collider Ring to Ion Collider Ring stacked spacing)
- Size and layout of tunnel to connect CEBAF to Collider Tunnel
- Diagnostics???
- Other parameterization???
- Electron Collider Ring
- Status: Origin defined – IP. Basic tunnel layout complete. Model of PEP-II RF Cavity ready for updated lattice. Assessment of “Moving Magnets” for synchronization done – can be adapted to new lattice and magnets. Vacuum elements are PEP-II style.
- Updated lattice file and layout – look at % fill (or free space for additional, not yet defined items)
- Resize tunnel to accommodate PEP-II RF Cavity spacing from floor/wall
- Add synchronization chicanes to layout
- Feasibility / sizing of new magnets
- Diagnostics???
- Abort/dump system???
- Other parameterization???
- RF HPA system basic model/layout – basic assessment of routing waveguides from surface to tunnel
- Low Energy Cooler
- High Energy Cooler
- Interaction Region
- Status: Region layout. 1st cut at IR FFQs and SD magnets – need to assess and iterate. Current model of IR beam pipe – ready for Impedance modeling. Magnet coils modeled.
- Iterate on magnet models
- Look at additional magnets for details – skew quads, correctors, anti-solenoids
- Baseline definition for supports, cryostats, etc.
- Magnet interactions
- Engineering Topics
- Superferric Magnets
- Normal Magnets
- SRF
- Crab Cavities
- Normal Conducting RF
- Feedback systems
- Diagnostics
- Controls
