Slava Derbenev

  • Completed an analytic estimations of space charge effect on the cooling electron beam at the ERL and the cooling solenoids and gave a talk at the MEIC accelerator R&D meeting
  • Continued MEIC conceptual design studies
  • Continued the organization work of COOL15 workshop and collaboration meetings
  • Gave two talks in Rick's cafe


Fanglei Lin

  • Looking at electron polarizations at high energies in the MEIC electron collider ring.
  • Provided various electron ring downstream chicane optics and beam sizes, required by nuclear physicists.
  • Continued working on establishing ZGOUBI, GPUSPINK and PTC.
  • Will attend the COOL15 workshop from Sep.28 to Oct.2.


Vasily Morozov

  • Ion polarization: helping Anatoliy's group prepare DSPIN presentation, racetrack booster, presentation at one of the R&D meetings.
  • Ion collider ring: exploring optics compensation schemes, holding teleconference with SLAC.
  • Detector integration: helping with electron polarimeter and beam pipe simulations.
