Sep 29 Agenda

• Mark- polarized positron capture up to 123 Mev media:Stefani9292021.pptx
• Discussion- Target geometry and beam size effects on emittance

• Standardize out we look talk about and look at Geant4/GPT,

• parameters upstream of target, what is target
• Geant4 distribution downside of target (500M events)
• GPT input description)
• number v. Z
• energy vs. Z
• energy spread v. Z
• bunchlength vs. Z
• emittance vs. Z
• beam size vs. Z
• polarization vs. Z

• Xelera proposal - A high-power positron converter based on a recirculated liquid metal in-vacuum target

• Geant4 simulations to evaluate/optimize target thickness for e+ yield/polarization distributions
• Intellectual effort to develop a Phase 2 framework for UITF installation &
• If helpful, could consider a trip to visit your lab
