The E835 charged trigger has been studied to select
e+e- events (inclusive and exclusive), phi-phi and elastic pbar-p events.
The single logics, based on the H2 hodoscope and on
the Scintillating Fiber Detector, are combined using
three Memory Look Up modules (MLU).
The C_MLU combines the logics based on H2, the P_MLU
combines, basically, the logics based on the SCI-FI bundles.
The outputs of the C/P_MLU are, in turns, combined in the M_MLU
to give the final triggers.
