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
