  1. QA/QC working group Working group 2014-02-20 ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  2. First questions QA/QC working group • Group organization • Mandate clarification & consolidation • Tasks & preview on work organization ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  3. Group organization • Members • Julien GIRAUD • Ralf HERTENBERGER • Francesco LACAVA (Contact person) • Sotiris VLACHOS • QA/QC meetings • Regular meetings • Vidyo (face-to-face if needed) • Frequency: every 2 weeks • Specific meetings • As often as needed for discussions on specific topics (in particular with other groups) • First meeting yesterday ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  4. Mandate From Mauro and Fabien Scope : The QA/QC here addressed mainly concern construction but not PCB QA/QC which is taken in charge by a different group. A link between these groups must be established. • Identify all individual components/parts to be labelled, recorded, individually tested and the parameters that should be recorded. • Identify checks needed during construction • Establish methods for the quality follow-up during the construction of the different parts at each construction site. • List the parameters and results of the checks to be recorded. • Establish the manual for the quality at the different phases of the modules construction. ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  5. Mandate consolidation (1/) • Implicit objectives: • to help defining all resources needed at construction sites • “Construction” • Identify & if possible define all the QA/QC tasks to be done during the construction Includingchecks, qualification and overall management • Questions for consolidation : • Items (except RO PCB) @ supplier subsidies (before delivery) to be considered? • Some operations @ CERN to be considered? • Limit with the services? • Be sure that QA/QC perimeter is not overlapping the one of another group ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  6. Mandate consolidation (2/) • Data needed: 1/ Identify all individual components/parts to be labelled, recorded, individually tested and the parameters that should be recorded. NSW-MM Identification & traceabilityrules List of parts & components Data needed by physics Check alreadyidentified Products to belabelled Parameter book (includingmaterial) General operationscheme @ construction sites Products to betested ATLAS-NSW identification rules ATLAS Identification & traceabilityrules Product parameters to berecorded ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  7. Mandate consolidation (3/) • Minimum list of checks asked by NSW-MM @ each construction site, to assure that module requirements are fulfilled • QA/QC group may suggest methods and instruments to do the checks. • The collaboration defines and qualifies the way and means to do the checks. • Data needed: 2/ Identify checks needed during construction Checkslist Product to betested General operationscheme @ construction sites List of parts & components Risks & acceptability Product parameters to berecorded Best practices & standards Suggestion for check methods ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  8. Mandate consolidation (4/) • Data needed 3/ Establish methods for the quality follow-up during the construction of the different parts at each construction site. Best practices & standards Methods for productqualityfollow-up Experiencefromotherprojects (Database) ATLAS qualityfollowingrules ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  9. Mandate consolidation (5/) • Including the parameters related to measure reliability • Data needed 4/ List the parameters and results of the checks to be recorded.

GIRAUD (20/02/2014)

  10. Mandate consolidation (6/) • QA oriented: Quality Manual • General rules to be implemented @ each construction site • For example: • Management of Non-conformities • Management of preventive and corrective actions • Management of recording • Management of configuration • Management of identification and traceability • Management of critical product • Management of assembly sequence and operation following • Management of delivery checks • Management of transportation from integration sites to CERN • Management of cleanroom conditions • Check, Test and Try • Management of Devices for check, test and try • Training of operator 5/ Establish the manual for the quality at the different phases of the modules construction.

  11. Tasks & workorganizationpreview • Consolidate the perimeter (no overlapping with other groups) • Define tasks • Define a schedule • Objective : work in parallel (fast track) • Define the groups in interface • Dispatch the work ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  12. First ideas(1/2) • Preparation of a list of the requirements to be fulfilled in each test. • From the WG on the requirements (planarity of the panels and positioning during the assembly). • From CERN rules (limits on the gas leaks? Other?) • Criteria for testing the mesh before gluing, for cleaning, for testing the tension. • Geometrical and mechanical tests on the single panel and on the assembled chamber. • Methods and instruments for the test. • For planarity: CMM machine, laser tracker, others? • For Mesh test: ……….. • For gas leaks: decrease in time of a small overpressure? Leak test with a He based leak detector for instance? Gas sniffers? • etc. ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)

  13. First ideas (2/2) • Definition of the tests needed during the different steps of the MM chamber construction. • Test of the components (thickness of : pcb for drift panels, honeycomb, frames etc.; test of the mesh, of other components) • Test during and at the end of the panels constructions (planarity, stiffness of the panel, mesh tension, deformations, …) • Test after the assembly (geometry, tightness of the chambers – gas leak, high voltage current leak, X-ray scanning ) • Final test (radioactive source, cosmic ray) • Test of sensors (B field sensors, alignment sensors, etc.) • Test in the construction sites (gluing farm, assembling farm) and at CERN before mounting on the NSW frame.
