Minutes of the UVic Testbeam meeting held Friday, September 3 2004
(present: TH, RK, ML, IG, AAgrewal, AAstbury, WS)
Michel pointed out that all the
various talks presented at larg week are available from the cern agenda
maker system. Specifically the links for all atlas meetings are
available here. To navigate
to a particular talk, say Tamara's LArg week talk, you would follow the
links in this way:
Liquid Argon Calorimeter ->
LArg Weeks ->
LArg Week September 2004 ->
CBT-EC2: EMEC/HEC/FCAL agenda link ->
EMEC/HEC 2002: Further Results on Hadronic Energy Reconstruction
transparencies link
There is some concern that linking directly to a talk there may
result in dead links later, hence the navigation procedure. Michel also
commented on TDC wrap around problems. It was expected that having two
TDCs would eliminate the 25 ns uncertainty in events that occur near
the TDC wrap around. However, events occurring near the wrap around of
one TDC occur near the wrap around of the other TDC.
Warren has updated his code on
lxplus to 8.6.0. This week he sat down with Michel to go over the
details of the sequencer. He has managed to hack Peter Lock's code
down to get just reconstructed energies for the FCAL, EMEC and HEC. The
code compiles fine but he encountered a problem when trying to run the
code. Michel and Richard commented that the problem is likely a result
of booking histograms in the initialize method rather then at the first
event, or to not booking the histograms at the first
event.
Tamara showed various plots
from her LAr week talk which can be found via the above procedure.
Richard commented that to better understand what was happening with her
error bars she should try 2-D scans of the Chi-squared while
minimizing at each step. Tamara also intends to do a global fit to obtain
beam energy independent weights.
Ashok recently realized that
the atlas software directory was lost in the June double drive failure
disaster. Since this discovery has only been made recently the TSM tape
backup has been overwritten. With the use of his valuable paper
notebook he has been able to install a recent atlas release. He also
noted that the distribution kit releases are slightly different then
the cern afs releases due to efficiency concerns.
Ian has been working down his schedule
for fixes to the LArG4TbEmecHec. Meanwhile Margret has been in
consultation with several people at cern regarding the future of our G4
efforts. He has also been working to install Geant 4.6.2 on the
fates.
