Rui Li
Previous two weeks (Feb 6-Feb 17) - Feb. 6-10: survey impedance budget studies, prepare and make presentation at the JLEIC R&D meeting - Feb. 13-18: understanding the state-of-art for the potential-well effect and the longitudinal single-bunch instability Next two weeks (Feb 20-Mar 3) - Feb. 20-26: understanding the logic and assumptions of ZAP, and see how its input can be related with the JLEIC database. Estimating JLEIC single bunch effects. - Feb. 27-Mar. 5: further understanding of the state-of-art for transverse single-bunch instabilities - Cheng-Ying needs more time to refine his thesis, so I expect to read and review it in a few weeks
