1. Impressions from CERN Elliott McCrory February 1, 2006

2. E. McCrory AD/HQ; LARP-doc-117 2/14 1 Feb 2006 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

3. E. McCrory AD/HQ; LARP-doc-117 3/14 1 Feb 2006

4. E. McCrory AD/HQ; LARP-doc-117 4/14 1 Feb 2006 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

5. E. McCrory AD/HQ; LARP-doc-117 5/14 1 Feb 2006 Orientation  Mike Lamont  Building 936  Prevessin Site  CCC is across the street  Building 874 CCC

6. E. McCrory AD/HQ; LARP-doc-117 6/14 1 Feb 2006 CERN Control Center

7. E. McCrory AD/HQ; LARP-doc-117 7/14 1 Feb 2006 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

8. E. McCrory AD/HQ; LARP-doc-117 8/14 1 Feb 2006 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.)

9. E. McCrory AD/HQ; LARP-doc-117 9/14 1 Feb 2006 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

10. E. McCrory AD/HQ; LARP-doc-117 10/14 1 Feb 2006 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.

11. E. McCrory AD/HQ; LARP-doc-117 11/14 1 Feb 2006 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!

12. E. McCrory AD/HQ; LARP-doc-117 12/14 1 Feb 2006 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?

13. E. McCrory AD/HQ; LARP-doc-117 13/14 1 Feb 2006 Full Moon on top of the Juras!

14. E. McCrory AD/HQ; LARP-doc-117 14/14 1 Feb 2006 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.
