Repetitive-Sequential 2: The Trigger is repetitive and Gate Width and Delay are varied
over the course of the measurement. Gate Width and Delay can be incremented in a
linear fashion or in an exponential fashion. Increasing the Gate Width is useful for trying
to find fine detail in a weak decaying signal. If you choose linear, you have to take a lot
more points. Exponential lets you take data points closer together where the signal is
changing rapidly and further apart where the signal is changing slowly.
• Single Shot: A single shot experiment is one where you’ve only got one chance to
catch the data. Any experiment that can’t be repeated more often than once a minute, such
as high power lasers, and explosives, is considered a single shot. You have to catch the
trigger when it comes. Prior to the event, the CCD runs in continuous cleans mode. You
don’t have the luxury of having the CCD just sitting there doing nothing because the
CCD will be accumulating dark current. When the trigger arrives, the intensifier gates, the
continuous cleans stop, and the array is read out with a minimum of dark current.
