2016-Feb-13 Accel. R and D Biweekly Report

Slava Derbenev

• Participated the JLab-Juelich collaboration meeting and gave a presentation
• Participated ERL cooler meeting and studied issues that could optimized bunched beam cooling
• Continued to study unified field theory

Fanglei Lin

• Working on the electron spin tracking using SLICKTRACK and ZGOUBI.
• Optimized the electron detector region optics and sent to M. Sullivan for studying of reducing the synchrotron radiation background.
• Miscellaneous: attended Juelich/COSY EDM discussion, discussed electron non-linear beam dynamics studies with SLAC colleagues, discussed the feasibility of polarized positrons for JLEIC, attended MEIC-related meetings.

Vasiliy Morozov

• Preparation of my AAC presentation: a number of dry runs and discussions
• Ion polarization: working with Anatoliy, presentation on EDM, setting up for tracking the ion collider ring
• Non-linear dynamics: working with Guohui and Fanglei, teleconference with SLAC
• GHOST development: preparation of a paper
• Miscellaneous: synchronization chicane, SBIR proposal, Skew PIC, injector discussion, positron discussion, detector region, seminar committee, translation of Slava's thesis

Amy Sy

• Skew PIC: Compensation of chromatic aberrations with straight and alternating strength sextupoles in the coupled correlated optics channel. Demonstrated that addition of sextupole magnets restores dynamic stability of off-momentum particles. Explored octupole insertion for spherical aberration compensation.
• ERL for isotopes: Committed to ODU CAS seminar in mid March.

Guohei Wei

• Combined multipoles survey of FFQ due to 10 sigma beam size of requirement at IP of the JLEIC ion collider ring.
• Learning on Hamiltonian and nonliear driving terms
• Writing of IPAC16's proceeding paper

Yuhong Zhang

• Wrote and revised slides for AAC review
• Participated discussions with Richard York
• Participated the JLab-Juelich collaboration meeting
• Continued JLEIC study
