The effect of window fraction on the deadtime of Anger cameras: concise communication.
The deadtime characteristics of an Anger camera are analyzed using a model consisting of a paralyzable front end and nonparalyzable display circuits. This model differs from previous deadtime analyses in that it considers the change in the fraction of counts passed by the pulse height analyzer as a function of the true count rate. Deadtime curves are analyzed for a Pho/Gamma IV Anger camera using 10%, 20%, and 35% windows.
