  1. Impressions from CERN Elliott McCrory February 1, 2006

  2. Outline • I was at CERN: 1/13/06 – 1/19/06 • The CCC • People • Zimmerman, Wenninger, AB/OP people, Limon, etc. • Implementing SDA for CERN? • Observations on CERN Control System • Other stuff • Installed wireless Web Camera • Left with Peter Limon • Fnalcam01.cern.ch • But must be on CERN campus net to see it E. McCrory AD/HQ; LARP-doc-117

  3. E. McCrory AD/HQ; LARP-doc-117

  4. Overall Impressions • French language is very important • They are busy • “What can you do for me?” • They are busy • We could begin to see some reticence in answering our remedial questions • CERN is vibrant! • Everyone is extremely friendly E. McCrory AD/HQ; LARP-doc-117

  5. CCC Orientation • Mike Lamont • Building 936 • Prevessin Site • CCC is across the street • Building 874 E. McCrory AD/HQ; LARP-doc-117

  6. CERN Control Center E. McCrory AD/HQ; LARP-doc-117

  7. Veronique Paris • Common Console Manager • Integrating old PS and SPS ways with new LHC ways • They have integrated several disparate work units at CERN into the AB Department • This is a BIG DEAL to them E. McCrory AD/HQ; LARP-doc-117

  8. Frank Zimmerman • Talked about CHEF at CERN • Gave him a demo of CHEF • Provided by Francois • They are interested • In the user interface by Francois, but • Need a compelling reason to invest time in it • We may be able to provide the expertise to demonstrate or to utilize it • (I sat in on an Optics meeting: Discussed dynamic aperture as it relates to the style of crossing, HH, HV, etc.) E. McCrory AD/HQ; LARP-doc-117

  9. Jorg Winnenger • Working on LOTS of things • Orbit compensation • Grad student: Ralph Steinhagen • Has analyzed archived orbit data from LEP • Thesis this summer? • Local vs. global correction? • Goal: 50 Hz Global Orbit Correction! • Other areas they would want to see developed: • Optics reconstruction/Beta Beating measurement • CHEF?? • Tune compensation (LARP already!) • Would gladly accept assistance • Would require ~1 week, face-to-face initiation E. McCrory AD/HQ; LARP-doc-117

  10. SDA for LHC • T. Bolshakov and I propose to supply Sequenced Data Acquisition (SDA) to LHC • Would benefit Fermilab • Get a better SDA system, we think • BerkeleyDB-XML (Sleepycat.com) • Improved modularization • Web-based interactions • AJAX instead of Java Web Start • Would require CERN workers’ help • Data acquisition “plug-ins” • Specifying SDA for LHC • Timofei is working on new SDA now: “Version 2.0.0” • He will create “To Do List” shortly • I am creating a detailed delineation of the high-level requirements from LHC@FNAL and from CERN for this application to be delivered • E.g., access requirements, DB replications, etc. E. McCrory AD/HQ; LARP-doc-117

  11. SDA for LHC: CERN people • Ronny Billen • Relational Database Guru at CERN • Seems willing to work with us to put SDA DB in a form they can work with • Not happy about XML DB! • Mike Lamont • Has assigned two people to help with this • Georges-Henry Hemelsoet • Visited Fermilab last summer • Jerome Axensalva • Likes the idea • But cannot think about it now! E. McCrory AD/HQ; LARP-doc-117

  12. LHC Control System: Observations • Suzanne will have more to say on this • Definitions • Campus Network • Something.cern.ch • Technical network (TN) • All the “front ends” • A couple of big omissions! • No role-based access yet • “No Packets Will Enter Or Leave The Technical Network” • I doubt that! • Once you are in the TN, there are no further restrictions • No “settings log” • If you get into the TN and make a mistake, then they should be recording these activities! • ACNET, EPICS, etc. all do this • And it has been deemed crucial to operations • Can/may we help with this? E. McCrory AD/HQ; LARP-doc-117

  13. Full Moon on top of the Juras! E. McCrory AD/HQ; LARP-doc-117

  14. Conclusions • CERN is a great place to visit now! • They have plenty to do • They can use dedicated help from us • If we can define the jobs we think we can do • I got positive noises from folks at CERN about SDA • Mike Lamont, for example. E. McCrory AD/HQ; LARP-doc-117
