Minutes of the Trigger Operation Meeting
(July 25, 2006)
Attendees: Rainer Bartoldus, Al Eisner, Fang Fang, Su Dong, Mark
Tibbetts, Dan Walker
No known significant events in trigger operations.
EMT dead time no longer significant after the slot-0 ROM fix, so that
Dan will try to reset the EMT FEX prescale back to 1.
Fang reported that new online release 13.11.0 is out (no DCT
changes) which needs cosmic validation. DCT online still running
against libraries in $ODF_ROOT/dct/, copied from releases, not yet from
the release itself. Move of relevant teststand code for calibrations to
L1DctCalOdf is done, but needs to be tested in the teststand first,
before going to the offline release. Because of the major change is CDB
from offline relesae 18->20, there is a backward compatibility issue
if we want make this working for release 18.
Offline release 18.7.0 is built 'just for Rainer' , primarily to fix
the L3 DCH high occupancy truncation problem (plus minor monitoring
updates). The prospect for deloying this is rather dim. Dave Hamilton
has been out of action for surgery and unclear when/how to get the
online build going for this. How to go about with offline validation is
also unclear. The full derivative code is still not in this
release which needs further validation. The concern is that although it
may be more efficient, there is a possibility that it may get over
zealous in finding tracks so that sometimes a fake track could take
away hits for a real track.
Data Quality and Monitoring
For the next step of testing
modified L1 configuration, if the only new object is the Zn, we
actually don't need to change GLT firmware, but simply use the current
Zk object for the 1Zn. It would be nice to really call it Zn in
TrgConfig but there is no real problem from calling it Zk since we
haven't used Zk in any real configuration. The test can therfore be
down without a new release. However, some work is need to create a new
ZPD configuration to change cuts for Zk, which we have to recreate
tools to accompolish and validate. Since offline analyses cannot deal
with GLT objects directly, we have to put Zk into the GLT configuration
to allow the analysis access. One suggestion is to put a prescale 1Zk
to displace the D2*&1M line.
