The timing for the STAR trigger is shown in the - Timing diagram. All of the timing for the trigger is controlled by the delay between the leading edge of the heartbeat (TS) provided by CAD and the occurence of the interaction. This delay is set by programmable delays on the RHIC workstation on the Shift leaders desk in the STAR control room for the Yellow ring V124 unit, channel 7. Once we get this correct, the rest of the timing internal to the trigger is ready, except for the BRB and YRB signals, which must be timed separately. The timing for these signals is also set on the V124 control pages, channel 2 in each unit.
