logo area Documentations List of Documents per Shipment  Certificate of Conformance for Delivery  List of spools (CERN and OST ID), Shipped Length, Order Length, Order Weight  Pedigree Report  Sub-Elements and ID of the raw material used in each billet  Raw Material Certificates  Production History  Pieces after intermediate draw (1.6 mm), pieces after final inspection, gross yield (km and %), phase when breakages or cuts occurred  QA Datasheets – Results of the measurements on the wire 11 T Wire: Procurement Strategy and QA/QC – B. Bordini5

logo area Documentations QA Datasheets – Meas. per Piece Length  Continuous measurements of the diameter, ovality and eddy current  At least * : 1 Copper to not-Copper, 1 Twist Pitch length and direction, I c and 1 RRR - (tail of the piece length) *Additional measurements: 1 Cu to not-Cu, 1 Twist Pitch, 1 I c and 1 RRR on the point of the piece length in the case of  the first delivered piece length of a billet  a piece length following a not delivered piece length 11 T Wire: Procurement Strategy and QA/QC – B. Bordini6 Each extremity of the delivered piece lengths are characterized ** XXXX X ** The X indicate the locations of the measured samples

logo area Documentations QA Datasheets – Meas. per Billet  2 micrographs (point and tail) with measurements of the minimum and maximum dimensions of the sub-elements  1 micrograph (tail) of the rolled wire  6 sharp bend tests (3 billet point, 3 billet tail)  6 spring back test (3 billet point, 3 billet tail)  1 I c of 15 % rolled sample (billet tail)  1 RRR of 15 % rolled sample (billet tail) 11 T Wire: Procurement Strategy and QA/QC – B. Bordini7

Bordini8

logo area Verification Measurements I c measurements per Quarter  200 km (about 50 % for 11 T and 50 % for MQXF) of wire and samples from 6 cables to be qualified per quarter  Verification samples (from the 200 km of wire):  Scenario I:  1 sample per piece length (+ 1 rolled per billet)  4.5 piece lengths per billet  132 measurements  yield equal to 80 %  Scenario II:  3 samples per billet (+ 1 rolled per billet)  96 measurements  yield equal to 80 %  Additional samples: 36 cable samples, 36 coil witness samples  In total 204 measurements in case of scenario I and 168 measurements in case of scenario II 11 T Wire: Procurement Strategy and QA/QC – B. Bordini9

logo area Verification Measurements Laboratory Capability per Quarter  Max I c test capability of the laboratory  6 samples per day (3 test stations)  Assuming 58 days per quarter (once having taken into account holidays and maintenance) 348 measurements  The laboratory would be occupied  58.6% of its capability in case of scenario I (204 I c measurements)  48.3% in case of scenario II (168 I c measurements) 11 T Wire: Procurement Strategy and QA/QC – B. Bordini10

logo area Approval Procedure Database: 3 phases approval procedure  The data from the manufacturer (QA datasheets) are in Excel format and are uploaded automatically in the CERN superconductor database  The results of the CERN verification measurements are also stored in the superconductor database  The approval procedure is managed via the superconductor database and it is divided in three phases: 1.Analysis of the manufacturer data: completeness and conformity. The manufacturer will obtain the green light for shipping the material only when this phase will be by approved 2.Analysis of the CERN Verification measurements: conformity with respect to the technical specification 3.Comparison between manufacturer and CERN data: the difference shall be limited 11 T Wire: Procurement Strategy and QA/QC – B.
