Feb 10 2017 JLEIC Ion Integration Meeting (and Notes)
Beam Parameter Spreadsheet
- Todd has developed a draft beam parameters spreadsheet, including input parameters and derived parameters
- Note that these are explicitly beam parameters, 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
