       synchrobetatron coupling and hopefully get a good injection
       simulation going.
     - VACATION: Oct 9

Chris Tennant

   Previous two weeks (Sep 18-Sep 29)
     - JLEIC: trying to benchmark Bmad for a single quad (elegant and DIMAD
       agree but use the same phase space coordinates while Bmad does
       not; tried (with Dave's help and a 30+ year old TN he wrote) to
       do the appropriate transformations. Still not making sense)
     - PERLE: learning/trouble-shooting Cheng-Ying's code for use with
       acceleration (to model S2E PERLE lattice)
     - JLEIC: summarizing results from analysis of CCR "simple arc"
       (microbunching is under control, one pass through arc is okay,
       10 passes through a ring comprised of arc and we're doomed -
       CSR longitudinal wake induced energy spread growth/distortion
       and CSR-generated emittance growth)
     - ADMIN: Neil symposium (Sep 27)
   Next two weeks (Oct 2-Oct 13)
     - CRADA signed? (a talk at the symposium raised the possibility
       of renewed interest in FEL for Navy and/or lithography in 2025
       time frame - woot!)
     - JLEIC: resolve Bmad issue and proceed to play with CSR/CSR
       shielding capabilities (benchmarking with elegant if possible)
     - PERLE: proceed with PERL analysis - really need some results
       for multiple turns. Suspect they are doomed too.

Randy Gamage

   Previous two weeks (Sep 18-Sep 29)
     - Dissertation writing: Continue coasting beam chapter, tech note
   Next two weeks (Oct 2-Oct 13)

Accelerator R and D (Y. Zhang)
Fanglei Lin

• Presented the progress on the study of the chromaticity compensation and dynamic aperture in the electron collider ring and discussed the design tasks of electron collider ring in the bi-weekly non-linear dynamics meeting.
• Redesigned the detector region optics in the electron collider ring and compensated the coupling effect due to the detector solenoid.
• Working on the presentation for the EIC collaboration meeting at BNL.
• Miscellaneous: discussion of spin tracking with Dave Sagan, attended the JLEIC R&D meeting, attended JLEIC parameter coordination meeting, attended JLEIC simulation plan meeting, attended JLEIC detector meeting.

Vasiliy Morozov

• Geometry tagging LDRD: simulations, data analysis, setting up for the next year
• Ion polarization: simulation of crab crossing effect on the ion polarization, teleconference with Anatoliy's group, DSPIN'17 paper
• Collider ring design: teleconference with SLAC, work planning
• Interaction region design: iteration on the magnet and correcting element design
• Lower-effort activities: crab crossing, planning of JLEIC R&D, seminar committee

Amy Sy

• Ran GEMC simulations for the geometry tagging LDRD project. Placed a virtual detector in the model for the interaction region - virtual detector was placed just beyond the final quadrupole of the downstream ion quadrupole triplet to tag all particles that pass through the quad triplet.
• Analyzed detected particles from GEMC simulations. Wrote python script to format GEMC output for conversion to root files for plotting. Generated plots of neutron multiplicity, proton multiplicity, change in rigidity, and a of residual nucleus vs nuclear thickness of the reaction.

Yuhong Zhang

• Attended COOL'17 workshop and gave a talk, discussed with cooling experts
• Gave a presentation on the topic of update of staged cooling scheme at the weekly JLEIC Accelerator Meeting
• Attended Neil Symposium
• Started study of JLEIC DC cooler
• Completed organization of EIC Accelerator Collaboration Meeting
