A second-generation fast kicker magnet (and its power supply) was designed by Fermilab for the SLC electron damping ring. The requirements were to inject and extract two bunches of electrons, with the following magnetic field specifications: Integral peak magnetic field = 0.021 T-m, Rise/fall time (0-100%) = 56.03 ns maximum, Flat-top duration = 61.62 ns. The flat-top does not imply a plateau, but two time-stable spots of equal magnitude, since the electron bunches are short (20 ps). Many of the early problems with these magnets have been studied intensely during the last two years, and substantial progress has been made. In particular, vacuum potting with room-temperature curing silicone rubber (RTV) has been refined to give reliable high-voltage service up to 18 kV/mm, and life-times of about a year despite stored beam intensities of 3 {times} 10{sup 10} electrons/bunch at 120 pps.
