IDDEFIX v0.1.1

IDDEFIX v0.1.1

Coming soon!

🚀 New Features

• Convolution and Deconvolution Utilities
  • compute_convolution(): perform wake potential convolution with a Gaussian bunch using different backends (numpy, scipy, scipy_fft).
  • compute_deconvolution(): estimate impedance from wake potential assuming a Gaussian charge distribution.
  • gaussian_bunch(): generate time-domain Gaussian profiles from RMS or standard deviation.
  • All functions now use standard deviation σ to match CST and physics convention.

💗 Other Tag Highlights

• 📁 Examples:
  • Added notebook 006 demonstrating convolution and deconvolution techniques using CST data.
  • Improvements to docstrings for all new utility functions.

🐛 Bugfixes

• Fixed notebook attachment error in example directory.
• Switched all wake potential calculations to use standard deviation σ instead of RMS bunch length, improving consistency with CST Wakefield and Wakis

IDDEFIX v0.1.0

IDDEFIX v0.1.0

🚀 New Features

• Smart Bound Determination (SBD):

  • Method to_table() to display the estimated parameter bounds.
  • Custom scale factors for Rs, Q, and fres: Rs_bounds, Q_bounds, fres_bounds for init.

• Utils:

  • Integration of neffint for non-equidistant Fourier transforms inside functions:
    • compute_neffint(): alternative to compute FFT.
    • compute_ineffint(): allows going from impedance to Wake potential, alternative to iFFT.
    • compute_deconvolution(): Allows going from wake potential to impedance using FFT(wake)/FFT(charge_distribution). Assumes charge distribution is a Gaussian with sigmaz specified by the user in [s].
  • File I/O:
    • read_txt(): reads ASCII .txt files into arrays or dicts.
    • save_txt(): exports x/y data to formatted .txt files.

• Framework:

  • In run_minimization_algorithm(), the argument margin now supports a list of independent values for [Rs, Q, fres], allowing finer control over parameter variations during optimization.
  • Updated docstrings for EvolutionaryAlgorithm methods for better documentation and clarity.
  • Check if beam sigma parameter is not passed when using wake potential functions and print a warning

• Solvers:

  • Implemented pymoo's CMA-ES algorithm (run_cmaes()) as an alternative global optimization solver.
  • Added run_pymoo_cmaes_solver() for CMA-ES optimization using pymoo, with support for custom population size, sigma, and stopping criteria.
  • Included an example integrating CMA-ES with previous optimization workflows.

💗 Other Tag Highlights

• 🔁 Nightly tests with GitHub Actions:
  • 001 -> Compare neffint, FFT, and analytical methods.
• 📁 Examples:
  • 004a: Fit directly the wake potential data with wake potential resonator formalism
  • 004b: Fit impedance from wake potential data using compute_deconvolution()
  • 005: Examples using pymoo's CMA-ES algorithm

🐛 Bugfixes

• SBD: Method find() now updates parameterBounds in self.
• Trimmed trailing whitespaces for improved code readability.

👋👩‍💻New Contributors

• @babreufig - Implemented the CMA-ES algorithm using pymoo in #3
