OutlineOutline 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


Overall ImpressionsOverall Impressions French language is very important They are busy

“What can you do for me?”

They are busyWe could begin to see some reticence in

answering our remedial questions

CERN is vibrant! Everyone is extremely friendly

Veronique ParisVeronique 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


Frank ZimmermanFrank 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.)


Jorg WinnengerJorg 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


SDA for LHCSDA 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.


SDA for LHC: CERN peopleSDA for LHC: CERN people Ronny Billen

Relational Database Guru at CERNSeems willing to work with us to put SDA DB

in a form they can work with• Not happy about XML DB!

Mike LamontHas 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!


LHC Control System: LHC Control System: ObservationsObservations

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?


Full Moon on top of the Juras!Full Moon on top of the Juras!


ConclusionsConclusions

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.
