Abstract
This paper reports the results of a study that empirically determined the gating time of an MCPI tube must be about eight times more than the iris time to prevent spatial resolution degradation. During the study, MTF curves were taken under dc conditions, as well as dynamic gating conditions from 1.6 microsecond(s) to 1 ns gate widths on a tube that has an iris time of 1.2 ns. Under dc conditions, the 50% MTF was 10 lp/mm; under dynamic conditions, the 50% MTF was 7 lp/mm from 1.6 microsecond(s) to 20 ns FWHM. However, when the gate width was reduced to 10 ns, the resolution began to decrease and became 5 lp/mm at 1.0 ns. The results of the experiment and the MTF measurement apparatus are discussed.
