Welcome and Introduction

Francesco Velotti

Classification

• Comparing accuracy vs speed
• Loss estimation: Can be combined with matter tracking (FLUKA, Geant4)
• No real improvements to be found on smaller machines?

Moving Forwards

• Accurate simulations with Xsuite - powered by GPU
• Extensible - can be used with pyCollimate (but is not GPU ready), or Geant4

Working Group goals

• A community for SloEx simulations
• Share tools and collaborate
• Can we exploit ML?
• Series of informal discussions
• Ideally sharing git projects
• Meetings every few months, or more frequent if needed

Questions

• Do we have a list of GitLab/GitHub projects?
• Codes for crystal bending - what do we have?
• Kevin Brown - working with a NASA group working on steering comic rays with crystals - could the same tools be used
• Next meeting - could everyone prepare one slide giving an overview for what everyone is working on?
  • Could we come up with a template of questions to answer?
  • There is also BDSIM - this can be used with GMAD
  • Collimation group in ABP
  • Crystal collimation can be done with SixTrack with K2 engine, or FLUKA, or BDSIM
  • This can be exported to Xsuite - still on going and crystal routine in K2 still not bechmarked with FLUKA
  • FLUKA can simulate interactions of particles with crystals
  • Measure response of the crystal, build a Probability Density Function
  • Use that in any simulation code - this is what we do in pyCollimate and mapTrack
  • We should keep track of our tools and what we use them for.
  • A list of techniques, or things people are struggling with.
  • Linking every presentation with a git repo, with examples
