9. 2/18/2006 M. Hohlmann - EMU meeting at Florida Institute of Technology 9 Update: Geometry COCOA: Alignment fits (now in CMSSW framework) COCOA IN Geometry of Alignment system XML files DONE: new COCOA version now in CMSSW; part of regular CMSSW releases (Pedro Arce) automatically converts old ascii geometry to new XML geometry files (Pedro) started testing this mechanism (MH) TO DO: define full ME alignment geometry in XML files (MH, Pedro Arce, Mike Case) test reading XML geometry into COCOA visualize alignment geometry in IGUANA; first attempt showed problems (MH, Mike) verify COCOA geometry against technical detector drawings

Hohlmann Calibs done; need to imple- ment (where?) / Need help Geometry: XML implementation StartedP. Arce, M. Case Automatic conversion from existing Cocoa files / ok (?) Geometry: Check against CAD Not started M. Hohlmann D. Eartly Can start once done with sensor calibs / Need help Implementation of Survey data Not started D. EartlyNeed help

14. 2/18/2006 M. Hohlmann - EMU meeting at Florida Institute of Technology 14 Readiness Review cont’d TaskStatusResponsibleComment/Projections Data Input Service to COCOA for fitting StartedM. Case, P. Arce Ok Output Service from COCOA fits to reco. Not Started M. Case, ?Need help IGUANA Visualization of COCOA results StartedM. Case, P. Arce, M. Hohlmann Ok, if initial tests work out as planned. Might need help from IGUANA experts A few general comments: In general, the ME al. group is quite short on manpower due to needs for commissioning the hardware M&O funding for FY06 will presumably not arrive at institutions, e.g. Fl. Tech, before March 06

15. 2/18/2006 M. Hohlmann - EMU meeting at Florida Institute of Technology 15 Summary Readiness for MTCC – slide by Oliver Buchmuller SW & Framework development - “tight” but OK Most important: Need to close the loop with Sub-detector community Faster Feedback - start testing! SW & DB Barrel/Link - “tight” Most important: Need to pick up developed SW, start testing, people involved have hardware & SW responsibilities SW & DB EndCap - on (very) critical path for MTCC Most important: We (CMS) need to find a way to support the activity ASAP - How?

16. 2/18/2006 M. Hohlmann - EMU meeting at Florida Institute of Technology 16 Team for Magnet test & Cosmic Challenge Onsite at CERN: –Vladimir Sknar (PNPI) → full-time for 3 mos. –Samir Guragain (Fl. Tech) → full-time for ~4 mos. applying for visas now exact arrival at CERN unclear because M&O funds are very slow in coming from FNAL… (hoping for early to mid-March) –Valeri Sytnik (Riverside) → “best effort” on Analog R/O –Dave Eartly (FNAL) → brief periods –Jim Bellinger (Wisconsin) → brief period for DCOPS R/O Offsite: –Fl.
