2016-Jun-26 Accel R&D Biweekly Report

Biweekly report (ended June 24, 2016)

Slava Derbenev

• Continued worked on bunched beam cooling R&D Explored new ideas/concepts on magnetized sources
• Communicated with Fermilab scientists to explore collaboration on cooling R&D
• Continued field theory study

Fanglei Lin

• Maternity Leave

Vasiliy Morozov

• Family medical leave most time
• Worked part time at office, on JLEIC
• Organized two teleconferences (dynamic aperture, and ion polarization)

Amy Sy

• Continued work on compensation of nonlinear effects for Skew PIC channel. Checking coupled correlated optics solutions with inverted tune ratio.
• Continued ERL merger studies in G4Beamline. Tracking particles through large aperture straight-toroid-straight sections to check matching and emittance growth of 20 and 55 MeV/c electrons. Particle tracking with and without transverse drift correction. Drift correction using both external dipole fields and tilted solenoid coils.

Guohui Wei

• Worked on multiple errors at the first week
• Vacation on the second week

Yuhong Zhang

• Presented JLEIC luminosity performance without cooling continued worked on the related issues, writing a paper
• Attended several JLEIC related meeting
• Started the cooling experiment data analyses
