Preliminary draft of PIP-II linac input file for ImpactX. Caution: This draft will require several updates.

  • Set up a TraceWin parser based on modifications to lume-tracewin
  • Construct a preliminary draft input file using default RF cavity and solenoid elements
  • Update quad and sol elements to support TraceWin units
  • Determine RF cavity absolute phase values, and correct the input file
  • Verify correct scaling/normalization of element field strengths
  • Preprocess field data files to extract Fourier components of 1D on-axis field

Follow-up:

  • Benchmark against TraceWin results

Examples for 3D space charge benchmarking
9e8a779 
- Modified the initial beam size in the IOTA lens benchmark example.
- Added 2 benchmarks of 3D space charge for initial testing.
- Add documentation for 2 benchmarks with space charge.
- Add a benchmark example with space charge and periodic s-dependent focusing.
- Added an s-dependent example using a Kurth beam without space charge.
- Modified tolerance for IOTA lens benchmark example.
  Reduced tolerance to account for smaller initial beam size and
  improved preservation of invariants of motion.
- Modified tolerances of space charge examples to allow CI tests to
  pass when space charge is not active.

- Modified tolerance for space charge examples.
  These should fail unless space charge is turned on.
