Annual Technical Report: 1 February 1989-30 June 1990 (Center forUltraviolet/Extreme Ultraviolet (UV/XUV) Research)

摘要

Research during this period has resulted in (1) the development of an activemagnetic shielding system to reduce the non-linear interactions between adjacent dipole and sextupole magnets in the Duke FEL storage ring, and (2) the development of an electromagnetic undulator with variable period to provide extended tuning range.
