CASA Accelerator R&D
Biweekly Report: 08/18/15 - 08/21/15
Submitted by: Yuhong Zhang
Continued design studies of MEIC, and developed a set of slides for the outstanding MEIC accelerator R&D issues
Worked with Rol Johnson, Vasily Morozov, Fanglei Lin, Amy Sy and Yuhong Zhang for new SBIR proposal
Worked with Yuhong Zhang on organizing the COOL15 workshop
Worked on electron polarization studies and reported in the MEIC R&D meeting.
Establishing the code ZGOUBI for spin tracking in the MEIC electron collider ring.
Installed and learning GUPSPINK with the help of Dan Abell from Tech-X.
Preparing a SBIR proposal for a storage-ring cooler for the MEIC.
Attended the discussion of bean synchronization in the MEIC.
Beam synchronization: presentation at the R&D meeting, beam synchronization report
Non-linear dynamics in the ion collider ring: teleconference with SLAC, working with Guohui
Isotope production: optimization of beam parameters at the radiator, simulations
Lower level activities: ion polarization, detector integration, skew PIC, electron cooling, SBIR
Continued work on skew parametric-resonance ionization cooling simulations. A look at off-momentum particles and sextupole effects.
Continued work on ERL/isotope production simulations. Study of UV FEL documentation for information on beam parameters, acceptances. Working on obtaining particle transport code MCNP6 for integration with MuSim and isotope production simulations.
Gave my first report at the MEIC Accelerator R&D Meeting. The title of the presentation is “First Look at error sensitivity in MEIC”.
Studied multipole magnetic field errors of the quadrupoles and sextupoles of the MEIC ion collider ring, and itheir effects on dynamic aperture
Studied field errors of FFQ (Final Focus Quadrupole) of the MEIC ion Ring, found about 10 % of errors due to normal quadrupoles, and checked shrinkage of dynamic aperture.
Took 3.5 vacation days
Organized three discussion sessions for MEIC beam synchronization
Developed new ideas for MEIC beam synchronization and presented at a MEIC accelerator R&D meeting;
Continued working on bunched cooling LDRD
Continued organization of COOL15 workshop
