A high-speed rotating shutter was designed to operate in a 10 exp -6 Torr vacuum at the optical focus of a laser spatial filter. The shutter is basically a wheel, with a single 3 x 10-mm slot at the perimeter, which rotates with a peripheral speed of 1 km/s. The motor to drive the rotating wheel is magnetically suspended and synchronously wound. The wheel achieves a 4 mu s opening time and a timing accuracy of better than 0.2 mu s.
