Several people were missing from this meeting due to unforeseen problems.
0) Milestones/Announcements/Followup (R. St. Denis)
Rick said that we are more or less on target with the milestones, but that
there has been a blockage due to missing data/bank definitions in 4152 .
Rick reminded people that there will be a set of meetings during the week
of the 27th over all the various aspects of Run2 databases. It is described
at Database Coordinator page
Rick was also interested in how the scripting was coming along for Run
Control. Jim P. said that it was not quite ready yet. It was also asked
if this scripting would be useful for DBANA, and the answer was no.
1) Missing Reports (J. Cranshaw)
Jack went through the emails he received from the missing gurus.
a. Database (R. Vidal) The production machine in B0 is still being
configured by Umesh.
b. SMX (S. Kuhlmann) The shower max now has the banks it needs defined
and is testing them.
c. Silicon (S. Nahn) They have been spending most of their time sorting out
hardware connection problems between SRC/TS. Some data has been written
to disk using the software event builder. It has not been looked at with
anything more sophisticated than od.
The software for making X-mode calibrations and putting the results in
a bank is under development. The SIXC bank is nearly defined. There may
also be a need for SIXP (peds,noise), SIXT (thresholds), and SIXG (gains)
bank definitions. There is a general agreement that 0.5 ADC counts is
sufficient resolution for the pedestal information. This gives an X-mode
calibration size of order 8Mb. There is also still an issue with the crate processor
handling the size and speed needed which is being resolved with the help of CD.
Work is also being done on how to do threshold scans and how to give the
bank the correct ending (D,C,P,T,G).
2) COT/Muon (A. Kotwal, B. Orejudos)
There have been discussions in the COT group on both Stage0 and alignment.
It is becoming clearer what Stage0 will actually want to store. Nobody
is currently working on the alignment, but Aseet has definite ideas about
how it needs to be done.
Most of the news involved the muon group getting into the act. They
have decided to monitor timing in the same way as the COT, although it
will serve purely as a diagnostic. They are working on X-mode bank
definitions following the same form as the COT. They can also simply
be added to the COT CalibConsumer as extra components. The CttCalibConsumer
will then morph into TDCCalibConsumer.
3) Calorimeter (V. Papadimitriou)
All of the central calorimeter ADMEMs have been installed. They have managed
to calibrate 15 crates of the central calorimeter in one run. Not all 15 were
certified, where certified means all channels have been checked and trigger
cables are connected. She showed a plot from DBANA which summarized the
percentage error on the slope for all 15 crates. There are some root
optimizations needed since the DBANA macro which created the plot took of
order 15 minutes to run.
Sergei B. asked several questions about source runs. His group is interested
in writing the consumer for the CHA source runs. Vaia said that source runs
would be the topic of one of the upcoming calorimeter meetings.
The other groups are included in the email summary or had nothing to report.
