QA/QC working group Working group 2014-02-20 ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014) 1 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) 2 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) 3 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. 1. Identify all individual components/parts to be labelled, recorded, individually tested and the parameters that should be recorded. 2. Identify checks needed during construction 3. Establish methods for the quality follow-up during the construction of the different parts at each construction site. 4. List the parameters and results of the checks to be recorded. 5. 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) 4 Mandate consolidation (1/) • Implicit objectives: Identify & if possible define all the QA/QC tasks to be done during the construction – to help defining all resources needed at construction sites • “Construction” ??? (@ supplier subsidies) Delivery from « suppliers » Storage Assembly Validation Packaging Shipment to CERN ??? (@ CERN) 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 group ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014) 5 Mandate consolidation (2/) 1/ Identify all individual components/parts to be labelled, recorded, individually tested and the parameters that should be recorded. • Data needed: List of parts & components Data needed by physics Parameter book (including material) ATLAS Identification & traceability rules Check already identified NSW-MM Identification & traceability rules General operation scheme @ construction sites ATLAS-NSW identification rules ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014) Products to be labelled Products to be tested Product parameters to be recorded 6 Mandate consolidation (3/) 2/ Identify checks needed during construction • 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: Product to be tested List of parts & components Product parameters to be recorded General operation scheme @ construction sites Best practices & standards Risks & acceptability ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014) Checks list Suggestion for check methods 7 Mandate consolidation (4/) 3/ Establish methods for the quality follow-up during the construction of the different parts at each construction site. • Data needed Best practices & standards Methods for product quality follow-up Experience from other projects ATLAS quality following rules (Database) ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014) 8 Mandate consolidation (5/) 4/ List the parameters and results of the checks to be recorded. • Including the parameters related to measure reliability • Data needed Product parameters to be recorded Checks list NSW-MM identification & traceability rules Best practices & standards Checks critical success factors Experience from other projects Checks parameters and results to be recorded Risks & Acceptability ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014) 9 Mandate consolidation (6/) 5/ Establish the manual for the quality at the different phases of the modules construction. • • • 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 Best practices & standards Experience from other projects Quality Manual proposal Risks & Acceptability ATLAS NSW - QA/QC working group - J. GIRAUD (20/02/2014) 10 Tasks & work organization preview • 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) 11 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) 12 First ideas (2/2) • Definition of the tests needed during the different steps of the MM chamber construction. 1) Test of the components (thickness of : pcb for drift panels, honeycomb, frames etc.; test of the mesh, of other components) 2) Test during and at the end of the panels constructions (planarity, stiffness of the panel, mesh tension, deformations, …) 3) Test after the assembly (geometry, tightness of the chambers – gas leak, high voltage current leak, X-ray scanning ) 4) Final test (radioactive source, cosmic ray) 5) 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.
