Rui Li

   Previous two weeks (June 25-July 6)
     - JLEIC: Presented the LCBI for Frank's new HOM coupler design at
       the impedance meeting.
     - JLEIC: Assessment of the behavior of collective effects in
       higher current regime of e-beam (E>10GeV), in responding to
       Yuhong's question for the high-energy JLEIC.
     - JLEIC: Collected the e-ring new parameters from Fanglei,
       Vasiliy will later send me new parameters for the p-ring. These
       may change the behavior of LCBI which is very sensitive to
       parameters.
     - JLEIC: Calculated growth time for the transverse coupled bunch
       instability (TCBI) for Frank's new HOM design using ZAP, and
       see no improvement of the growth rate for the new HOM coupler
       design from that of the old one.
     - JLEIC: Working on the Mathematica calculation of TCBI, so as to
       identify the HOM resonance that gives dominant contribution to
       growth rate, so the RF people can work on mitigation of these
       HOM.
   Next two weeks (July 9-July 20)
     - JLEIC: Finish my part of the ICFA newsletter writing
     - JLEIC: Continue to finish the Mathematica calculation of TCBI
       and its comparison with ZAP
     - JLEIC: Summarize the LCBI and TCBI results for exchange with
       the RF people
     - JLEIC: Estimate the resistive wall impedance in JLEIC e-ring
       and ion ring

Edy Nissen

   Previous two weeks (June 25-July 6)
     - JLEIC: Answered LDRD questions posed by reviewers
     - JLEIC: Created presentation slides for LDRD review
     - JLEIC: Determined that the acceleration anomaly in synergia is
       caused by space charge, not bucket shape changes or higher order
       nonlinear dispersions.
     - JLEIC: Gave LDRD Presentation
     - VACATION: June 25, July 2-3
   Next two weeks (July 9-July 20)
     - JLEIC: Work on booster working point simulations to eliminate
       the acceleration anomaly
     - JLEIC: Work with summer student on injection modeling for the
       booster
