Effect on Time Resolution of Ambient Gas around Rotating Mirrors

John K. Landre

Tests on streak cameras equipped with rotating mirrors show that the best time resolution is obtained with the mirror spinning in a vacuum. Contrary to common belief, the next best resolution occurs in air, rather than in helium. Although the mirror can be operated much faster in helium, gas turbulence produces poorer time resolution. These results were obtained by putting a Model 770 Streak Camera in autocollimation.
