Upcoming for January
• I&T deliverables
– Keep working on TKR Tot
– Keep working on more sophisticated CAL calibrations based on
what’s been learned during assembly at NRL
• Gino pipeline functioning
– Keep testing it
– Ran 2 allGamma MC runs over Xmas (twice, in fact)
• Completely smooth. Now have tools for metering MC jobs into
the pipeline and for accessing the data catalogue from
compiled code
• TkrRecon upgrade
– First major tag released 1/4
– Plan to run 1M allGammas to see how it looks
• CalRecon upgrade (Nov-Jan probably) – repeat from Dec report

Issues & Concerns
I&T support has been heavy load
Hardware will start arriving sometime… all our pieces have to be
in place.
Thinking about DC2 – must juggle I&T support with DC schedule
Getting the background rejection done in a timely fashion will be
hard. May need to start it in parallel with CalRecon revamp
