A phase synchronization system of high-speed (up to 4 × 10⁴ frames/s) photographic shooting on two BΦY-1 units used for studying a vacuum arch is described. The design alterations brought into the BΦY-1 unit and the designed electronic control circuit allowed one to obtain one- to two-frame phase synchronization and 0.2% rate errors using comparatively simple methods.
