QA/QC meetingsRegular meetingsVidyo (face-to-face if needed)Frequency: every 2 weeksSpecific meetingsAs often as needed for discussions on specific topics (in particular with other groups)

First meeting yesterdayATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)3MandateFrom Mauro and FabienScope : 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 constructionEstablish 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)44Mandate consolidation (1/)Implicit objectives:

to help defining all resources needed at construction sitesConstructionATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)5Identify & if possible define all the QA/QC tasks to be done during the construction Including checks, 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 groupMandate consolidation (2/)ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)61/ Identify all individual components/parts to be labelled, recorded, individually tested and the parameters that should be recorded.Data needed:List of parts & componentsParameter book (including material)ATLAS Identification & traceability rulesData needed by physicsGeneral operation scheme @ construction sitesATLAS-NSW identification rulesCheck already identifiedProducts to be labelledProducts to be testedProduct parameters to be recordedNSW-MM Identification & traceability rulesMandate consolidation (3/)ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)72/ Identify checks needed during constructionMinimum list of checks asked by NSW-MM @ each construction site, to assure that module requirements are fulfilledQA/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:

List of parts & componentsGeneral operation scheme @ construction sitesChecks listRisks & acceptabilityBest practices & standardsProduct to be testedProduct parameters to be recordedSuggestion for check methodsMandate consolidation (4/)ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)83/ Establish methods for the quality follow-up during the construction of the different parts at each construction site.Data neededBest practices & standardsExperience from other projectsATLAS quality following rulesMethods for product quality follow-up(Database)Mandate consolidation (5/)ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)94/ List the parameters and results of the checks to be recorded.Including the parameters related to measure reliabilityData neededNSW-MM identification & traceability rulesChecks listChecks critical success factorsBest practices & standardsExperience from other projectsRisks & AcceptabilityChecks parameters and results to be recordedProduct parameters to be recordedMandate consolidation (6/)ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)105/ Establish the manual for the quality at the different phases of the modules construction.QA oriented: Quality ManualGeneral rules to be implemented @ each construction siteFor example:Management of Non-conformitiesManagement of preventive and corrective actionsManagement of recordingManagement of configurationManagement of identification and traceabilityManagement of critical productManagement of assembly sequence and operation followingManagement of delivery checksManagement of transportation from integration sites to CERNManagement of cleanroom conditionsCheck, Test and TryManagement of Devices for check, test and tryTraining of operator

GIRAUD (20/02/2014)11First ideas (1/2)ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014)12Preparation 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.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.
