Beam Parameter Spreadsheet
- Todd has developed a draft beam parameters spreadsheet (png), including input parameters and derived parameters
- Note that these are explicitly beam parameters, (mostly) not accelerator hardware parameters (e.g. lattices, instrumentation, etc)
- Should we make the case to reorganize the parameters wiki area to separate beam and lattice parameters?
- Three goals:
- Ensure consistency of design beam parameters at matchpoints between JLEIC machines
- Provide input to impedance and instability calculations, and broader beam simulation effort
- Serve as a machine-by-machine beam parameter reference for the eventual CDR
R&D Items: Ion Integration
- Bunch formation (Jiquan, Todd, Randy; Ed, Vasiliy)
- Most pressing immediate need is to characterize bunch formation plan through Booster and Collider rings
- All beams start as coasting beams at Booster injection, so no major impact from ion source/ion linac parameters
- Ion source (Amy) / Linac (Todd/Brahim) / LtB / Booster injection (Ed)
- Linac cost
- Pulsed ion QWR/HWR gradients and RF control
- Booster space charge control
- Booster injection design
- Transverse/longitudinal emittance budget vs DC cooling
- Polarization
- Booster extraction (Ed/Todd?) / Booster to Collider (Todd, Yves?) / Collider injection (Vasiliy?)
- Bucket to bucket synchro/cogging?
- Final beam stripping
- Polarization (AGS to RHIC transfer spin design chapter)
- Coordination with other groups
- Beam cooling (Steve Benson et al.: Booster DC, Collider)
- Instability/impedance (Rui Li et al.)
Reference Materials
- JLEIC Fall 2016 Collaboration Meeting (Oct 5-7 2016, InDiCo)
- JLEIC svn repository
- Last meeting (Jan 13 2017)
Attendance
- TBD
