Rui Li

 Previous two weeks (Feb 6-Feb 17)
   - Feb. 6-10: survey impedance budget studies, prepare and make
     presentation at the JLEIC R&D meeting
   - Feb. 13-18: understanding the state-of-art for the
     potential-well effect and the longitudinal single-bunch
     instability
 Next two weeks (Feb 20-Mar 3)
   - Feb. 20-26: understanding the logic and assumptions of ZAP, and
     see how its input can be related with the JLEIC
     database. Estimating JLEIC single bunch effects.
   - Feb. 27-Mar. 5: further understanding of the state-of-art for
     transverse single-bunch instabilities
   - Cheng-Ying needs more time to refine his thesis, so I expect to
     read and review it in a few weeks

Ed Nissen

     Guinea Pig for 4/3 gear changing evaluation
   - JLEIC: Finish literature search, start documenting parameters
     for calculations and future simulations

Chris Tennant

 Previous two weeks (Feb 6-Feb 17)
   - JLEIC: analysis of CCR-like arc with collective effects (space
     charge, CSR, space charge + CSR) (it ain't good)
   - JLEIC: analysis of mitigation of CSR wake using RF cavity in
     circulator ring (still ain't good)
