Setup
MCP Bracket pulse implementation is accomplished by selecting Bracket Pulsing ON
from the host software. Figure 22, is a timing diagram for bracket pulsing. Insertion delay
between trigger and T0 is ~ 12 ns. Insertion delay to photocathode gate is 35 ns (i.e., the
minimum delay in bracket mode is 35 ns): this delay allows the MCP to be up to “full
gain” before the photocathode is gated on.
Note:
Because Gen III Intensifiers do not respond in the UV, bracket pulsing is not
available for these intensifiers.
