Abstract :
The flood beam in a direct view storage CRT must uniformly illuminate the storage surface. Variable persistence operation of the CRT also requires that the electron trajectory at the storage surface be within about 5 degrees from perpendicular. Thus, an initially diverging beam must be collimated near the screen.
