Nov 16 2017 JLEIC Ion Bunch Formation Meeting

  • Todd, Yuhong, Jiquan, Ed, Randy (Vasiliy)

Objectives

  • Summarize existing baseline bunch formation scheme
  • Identify any concerns with existing baseline bunch formation scheme
  • Develop short-term plans to address any concerns
  • Document baseline bunch formation scheme (for TDR and Randy's dissertation)
