1. The FiDeL Database Per Hagen (TE/MSC) 02.07.2009 Acknowledgements: L. Deniau, R. Wolf …

2. Where is FiDeL data stored? 2 Since 2007 official data stored in web site http://cern.ch/fidel It has all official REFPARM data, but only partial complete wrt REFHARM measurements and analysis Currently, “work in progress” for 2009, stored in \\webh11\lhc-div-mms\tests\MAG\FiDeL_reports Official “table data” stored in central Oracle database: user: fideldb password: ********* database: accdb This database is read-only so do not worry! Tool to access: Golden from Benthic Software or Oracle SQL client from central UNIX service Uploading and change of FIDEL data must be done by designated person (2008 + 2009 = contact Per HAGEN)

3. 3 Installing Benthic Golden Only for Windows platform (can be used in Windows emulator/virtual machine for Macintosh platform) How to get started: Use Google to search for: Benthic Golden Download Golden See license keys in \\cern.ch\dfs\Applications\Benthic\\cern.ch\dfs\Applications\Benthic Expert contact point in CERN: Oracle.Support@cern.ch but Golden support seems to be “as is”Oracle.Support@cern.ch

5. 5 REFPARM (model parameters) REFPARM_2008 contains the parameters used in 2008-09 REFPARM_2009 contains the new parameters for 2009 + 2008 parameters which have not changed This allows us for having versioning (history for major releases) REFPARM gives access to all (versions of) parameters Table contains all fields as specified in EDMS 908232 + 2009 “penetration” + Comments + Approved (yes=official) + User_Id (main contact) + Ref_date (date valid) + Circuit_Id (for convenience) + Magnet_Type () REFPARM_200x_EXPANDED (x=8 or 9) gives final coefficients for magnets and circuits by substituting references to other records, like generics.

6. 6 select * from refparm where user_id = 'ldeniau' and ref_date > to_date('01-01- 2009','DD-MM-YYYY') order by item_id; Examples of REFPARM SQL select user_id, ref_date, count(*) nrec from refparm group by user_id, ref_date order by user_id, ref_date; select circuit_id, count(circuit_id) nbycircuit from refparm_2009 where circuit_id is not null and harmonic = 'TF' and magnet_type='MQ' group by circuit_id; Has my 2009 data been published? Manager’s view of who has done what How many apertures are connected per MQ circuit?

8. 8 REFDESC + MAD_SEQUENCES (LHC magnet layout in tunnel) MAD_SEQUENCES, MAD_SEQUENCES_200x (x=8 or 9) are references to the official LHC layouts. It contains a lot of information. REFDESC_200x (x=8 or 9) are static records (stability) based upon LHC layout. They contain a small set of parameters + extra fields deemed useful. Versioning concept is the same as for REFPARM. Main fields: MAD_NAME (as used in LHC MAD optics) Position (absolute s-coordinate, ATLAS IP=start) Magnet_Name (the most reasonable LHC identifier from layout!) RING (I = Inner or E = External) CIRCUIT_ID (logical name of power supply) CONNECTION_SIDE (U = Upstream = CS->NCS in s-direction, D = Downstream = NCS->CS = π-rotated around vertical axis and magnetic measurement frame) TOP_ASSEMBLY_NAME (official slot id) = cryostat assembly or standalone magnet or instrument etc BEAM (1, 2 or 12) APERTURE (1 = V1 or 2 = V2)

9. 9 Examples of REFDESC SQL Overview of all circuits select circuit_id, beam, count(*) nmagnets from REFDESC_2009 group by circuit_id, beam order by circuit_id; select * from REFDESC_2009 where circuit_id='RB.A12'and beam=1 order by position; Select one circuit for beam 1

10. 10 REFHARM (Magnetic measurements in normalised format) See description of REFHARM in http://cern.ch/FiDeL web Additional fields: Comments User_Id (main contact) Ref_date (date valid) select * from REFHARM where magnet_name like 'HCMBRC%‘ Please help us by checking if your data is loaded here (after validating the data for FiDeL model) As of today I am confident we are missing a lot of data
