Abstract
n order to study a dynamical property of a vertical instability, we have developed a pulse octupole magnet system. The magnet can be operated with magnetic field rise and fall time of around 1.2msec, respectively. The maximum integrated field strength reach up to 2600T/m2. We measured the dynamical behavior of the vertical instability using the pulse octupole magnet for a multi-bunch beam of 400mA. We found that the growth time of the instability was longer than the suppression time.
