Overview of End to End Runs
• We successfully completed all end to end runs for Tower A
• The infrastructure for data analysis is in place and working
well
– All plots in this presentation were obtained from the SVAC
reports which are automatically generated at the end of the
runs
– Please use them and give us feedback
• Two tower tests will occur in 1 to 2 weeks
– We need to look at these data to provide inputs to the test
plan

Retrieving end to end runs
• Go to the Runs database
• To get all runs Query on
– Script name: end2end
– Completion Status: PASSED
– Duration: > 100
– Bear in mind that Americium runs are 1 min long !
• Look at Config report and digi and recon reports
– Currently we are updating the reports based on the results
from these runs
– Comments are welcome
– Please come to our Friday meetings if you want to
participate

Demonstrate that the pulse generator works as expected.
– Do we have all the configurations we need to understand the
behavior at high rates?
– Should we lower the CAL LAC threshold (for one column) to load
the CAL with data and allow a fair comparison of deadtime?
Do files sizes and deadtime make sense for the possible permutations
of the main register configurations?
– (1/4) CAL range readout, zero suppression (ON/OFF), TEM
diagnostics (ON/OFF)
Are there differences in distributions that could be ascribed to
different timing when reading out only from LO or HI side of TKR
cables?
– Of course use baseline as a reference
Are there idiosyncrasies in the Error events?
– Need to explore in electronics and physical space
Need to study topologies and rates of different trigger types
– As many runs as possible
More ideas?
– Volunteers?

Summary
• This week we all made an spectacular progress !
– Thank you all
• Today we will change the code in the pipeline (bug fixes)
– We will reprocess all runs
• Depending on your analysis you do not need to wait for the
pipeline
– Go ahead and adopt a run
• Please let me know how you want to contribute for the data
analysis
– We need to plan quickly for the two tower tests that will
happen in 1 to 2 weeks
