Slava Derbenev

  • Studied the beam synchronization issues for MEIC, initiated and coordinated technology R&D for supporting the scanning synchronization scheme
  • Gave a presentation on scanning synchronization scheme at the special MEIC R&D meeting
  • Worked with Yuhong on selections of the invited presentations at COOL15 workshop
  • Worked with a selection committee for identifying candidates for Dieter Mohl medals/prize, which will be presented at COOL15 workshop
  • Gave two presentations at Rick's Cafe


Fanglei Lin

  • Established the storage-ring cooler optics and calculated electron beam characteristic parameters.
  • Continued working on the improvement of code SLICKTRACK.
  • Installed the spin tracking code ZGOUBI and establishing the environment for the electron spin tracking.
  • Did a literature search of RF acceptances and energy spreads in other accelerators for dynamic aperture studies.
  • Attended special MEIC R&D meeting on the topic of beam synchronization and other MEIC-related meetings.


Vasily Morozov

  • Nonlinear dynamics in the ion collider ring: nonlinear analysis, tracking, working with Guohui, holding a teleconference with SLAC, setting up for studying attice errors.
  • Study of conventional beam synchronization schemes, preparing and making a presentation at the mini-workshop.
  • Ion polarization: studying racetrack booster option, modifying figure-8 lattice into a racetrack, holding a teleconference with Anatoly's group.
  • Lower effort activities: isotope production, skew PIC, beam-beam, electron cooling, detector integration.


Amy Sy

  • Continued work on parametric-resonance ionization cooling. Further investigation of fringe field effects and beginnings of aberration compensation simulations.
  • Fast kicker LDRD simulations in support of Andrew Kimber's S&T talk.
  • First optics simulations for isotope production STTR using MuSim.


Guohei Wei

  • Installed software package Virtual box, Ubuntu Linux, Elegant, DDSPLOT, and MADX
  • Initated dynamic aperture study for betatron tune scan in the ion collider ring.
  • Conduced a survey of error studies of several accelerators in the world including PEP-II, KEKB, SuperB, NSLS-II, RHIC,J-PARC and LHC, in order to start error study of our ion collider ring


Yuhong Zhang

  • Took 2.5 days off (for family medical issues)
  • Organized a special MEIC accelerator R&D Meeting on beam synchronizations
  • Also spent some time to review and study the conventional beam synchronization issue, explored a couple of new ideas and plan to continue this study in the next couple of weeks with several colleagues (Fanglei, Vasily, Slava and Jiquan)
  • Continued LDRD study
  • Nearly completed selection of the invited presentations for COOL15 workshop with Slava
