Status: the starting point August 2004
Request for SSS measurement at Bldg 904 Dipole geometry measurement software needed operation by expert Each magnet should be connected separately (stop at the beginning
of each aperture) My request to switch to a more user-friendly control software because:
The software has collected a series of “irreversible” bugs along its modifications
The measurements are often interrupted due to communications problems between softwares
Subcontractor will perform measurements The polarity tester (Mouse) has proven that the level of automation can be
drastically increased The analysis is performed off-line by one person (>1day per analysis)
The team of C.Charrondiere suggests to change the control software (to GEAX) (many thanks for the excellent work)
Quick shift to a newly conceived system with a new control software with the aim to provide a fast and accurated system

Foreword: famous quotes
Never discourage anyone...who continually makes progress, no matter how slow - Plato (427 BC - 347 BC)
Plato is boring - Friedrich Nietzsche (1844 – 1900) An eye for an eye makes the whole world blind - Mahatma Gandhi,
(attributed) (1869 – 1948) Beware of the young doctor and the old barber - Benjamin Franklin (1706
– 1790) Success is not the result of spontaneous combustion. You must set
yourself on fire – Reggie Leach Well begun is half done – Aristotle (384 BC – 322 BC) Your descendants shall gather your fruits – Virgil (70 BC – 19 BC) It is rash to condemn where you are ignorant – Seneca (3 BC – 65 AD) It is pleasant at times to play the madman – Seneca (3 BC – 65 AD) The accuracy? It’s better than 0.1mm – J.Garcia-Perez We can do a full SSS measurement in 4 hours or less… - J.Garcia-Perez

Upgrade steps
My statements: 1 year ago: “I’m a magnet guy: I can design and build a 12T
Nb3Sn field quality magnet in 8 months…” (too many beers?) Mid-August: “I will need 1 month to get the AC mole system
roughly working” Beginning of September: “If I follow closely the analysis done by
hand, I will take a long long time to establish automation. Nonetheless an automatic analysis will take few minutes”
October: “In two weeks the system will be able to measure in 5-6 hours”
November: “For the first week with 5 measurements I will pay a drink for the “release” of the system”
3 December: “The mountain of SSS in Bldg. 904 has finished… I can’t believe it! I’ll pay a drink!” (comment: no drink yet!)

Upgrade Plan
The mole-camera relative position will be checked at each measurement step Stop the measurement and change mole or algorithm to correct
in the soft (0.1FTE/month) The field angle is included in the measurement and a
solution to the poor accuracy has been solved at a first stage Angle data will be quick to check right after the next
measurements (~0 FTE) Polarity test
Based on full harmonic acquisition (0.5FTE/month) All the previous points depends on software
development team availability

Results
Optics method (mechanical axis) Saw tooth solved Accuracy of 0.1mm proven with calibrations (and, yes,
cross-checks with geo-mole) Harmonics method (magnetic axis)
Saw tooth to be checked to go below 0.2mm with a confidence margin
Accuracy/repeatability proven many times to 0.1mm But sometimes…
[email protected] 1011 February 2005
Do we need to repeat old measurements? “Old” measurements have been corrected offline with a
realistic method The subcontracting measurement team will have very
soon a table with the parameters to enter for analysis Follow-up to check if this organization works
At present the SSS: 1,4,16,20,24,31 data have been submitted to the MEB indicating that the accuracy is 0.2mm
All the others are measured with accuracy within 0.1mm Note that vertical gives you the repeatability In case something looks wrong we will flag it
[email protected] 1111 February 2005
Conclusions
The organization of the system upgrade has been focused on the development itself rather than on measuring measuring measuring.
The organization of the analysis has been focused on developing the analysis software rather than utilizing sometimes days for the analysis of an SSS.
3 months full commissioning of the system for operation Additional 3 months for finalization of the analysis tool
(mainly done by C.Charrondiere and R.Gorbonosov) and to find/prove a realistic reliability of the data (team work)
