2015-06-26 Accelerator R&D Report
CASA Accelerator R&D
Bi-weekly Report - due 06-26-2015
Submitted by Yuhong Zhang
- Continued to develop the matched electron Cooling concept. To be reported at COOL ’15 (Sept. 28 – Oct. 2)
- Discussions with Grigory Kazakevich and Vladimir Popov on scanning synchronization for MEIC (advanced magnetron source phase/amplitude control of coupled cavities and search/study for superfast RF switches.
- Had meeting with Fulvia to propose and discuss:
- TeleConf. meeting on Scanning Synchronization and magnetron developments.
- Response from Fulvia: Conduct it on July 3.
- Assisting Yuhong Zhang as Organizing Co-chair Cool ‘15 International Workshop.
- Continued work on parametric-resonance ionization cooling.
- Investigation of fringe field effects using single lumped elements and sliced dipoles for both uncoupled and coupled correlated optics conditions
- Gave a 1 hour presentation on PIC background and recent progress at the MAP-related bright muon sources phone meeting.
- Optimized optics in the matching and spin rotator sections to reduce the MEIC electron emittance.
- Revisited the continuous injection scheme for the MEIC electron collider ring.
- Provided the required beam parameters to nuclear physicists for their studies of downstream ion beam line.
- Establishing the GPU environment for the code gpuSpinTrack (with Dan Abell, Tech X) for spin tracking of ion beams
- Collected and submitted publications in the past 3 years to JLab publication database for the S&T Review.
Vasily Morozov • Tracking the ion collider ring and communicating with SLAC group. • Miscellaneous (lower-effort activities): o communicating with Anatoliy's group, o communicating with the detector design group, o GPU tracking code (GHOST) development, o Skew PIC development.
Yuhong Zhang • Explored new ideas for electron cooling and gave a presentation at the MEIC R&D R&D meeting • Continued development of the LDRD work
• Worked with Slava and the committee on selection of the invited speakers at the COOL'15 workshop • Assisted Fulvia on the MEIC R&D planing, including a half-day special R&D meeting (on July 24) for beam synchronization study
In the next two weeks • The first new MEIC postdoc, Guohui Wei, will started today, working on nonlinear beam dynamics with Vasily • The second new MEIC postdoc, Hisham Sayed, will start on July 1, working on electron cooling. (He is in Yves's group)• The first R&D meeting for cooler development will be held on July 9.
