Oct 6 2017 JLEIC Ion Integration Meeting

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
    • Have input from
    • Have requested input from Steve (cooler) and Brahim (linac); will continue arm-twisting at collaboration meeting.
    • Identify transport line owners; will likely be Yves (electron) and Todd (ion) at present
  • 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
