[Primexd] Primex Daily Meeting

[Alexander Somov]

Hi Ashot, All,


I am working on implementing triggers from CCAL (and likely FCAL) now.

Those triggers are ancillary, but it would be practical to have them in 
addition

to the main production trigger.  I use BCAL as a separate trigger type 
in GlueX.

I will need to do some beam tests  before I add them.


Implementing the "efficiency trigger"  is more complicated. Similar

to GlueX, I am thinking of using some TAGH counters in coincidence with ST

(or simply ST hits ) for this. Timing has to be adjusted properly in order

to minimize "wrong" assignment of trigger bits  (I'll need to check 
accidentals).


Cheers,

        Sasha
