Rui Li

• Previous two weeks (July 23-Aug 3)
  • JLEIC: Calculate resistive-wall impedance contributions to the coupled bunch instabilities. Found out that for the electron ring, their effects are negligible for the longitudinal coupled bunch instability, but they play a major role for the transverse coupled bunch instability (dominant over the RF cavity HOM effects).
  • JLEIC: Summarize the LCBI and TCBI results and presented them at the impedance meeting
  • JLEIC: Review early literatures on collective instabilities
• Next two weeks (Aug 6-Aug 17)
  • JLEIC: modify the section of preCDR to include new findings of resistive wall effect on CBI
  • JLEIC: continue to develop more understandings on collective instabilities by going over literatures
  • JLEIC: digest discussions on the impedance meeting, forming up my vision for the impedance studies

Edy Nissen

• Previous two weeks (July 23-Aug 3)
  • JLEIC: Booster working point simulations, up to 96% survival but still with long-term beam stability issues
  • JLEIC: Update pCDR contribution based on reviewer feedback
• Next two weeks (Aug 6-Aug 17)
  • JLEIC: Continue Booster working point simulations
  • JLEIC: Assist with pCDR as necessary (referencs, tables, Booster section)

Chris Tennant

• Previous two weeks (July 23-Aug 3)
  • LERF: LERF lattice study for isotope production (no constraints)
  • ADMIN: planning mini-ERL workshop
