Trigger Rates

For the August 2002 beam test, the DAQ system was pushed to an event rate of around 6kHz. This corresponded to a fairly low live time of about 20%. For PrimEx production running, we will run such that the live time does not fall below 80%. This will correspond to a DAQ rate of approximately 3 kHz. A summary of the primex triggers and their anticipated rates is shown in table 1.2.5.

Table 1: Triggers that will be used during primex and their anticipated rates during production running.

Trigger	Rate
$\pi ^o$	2 kHz
PS	10 Hz
LMS	2 Hz
Clock	1 kHz
Total	3kHz
