A. Bignami on behalf of LASA SRF Group LASA The external QC: Status/Results on “real” cavities M001÷M002 / P05 & MBLG002 A. Bignami on behalf of LASA SRF Group 9th SRF Collaboration Meeting – ESS, November 6th-7th 2018

Main issues Status of documents flow for the series production: Subcomponents Al1÷Al3 Al4 Al5 Status of NCR flow: minor NCR major NCR The ESS_LASA_DMS for: document management data analysis

The acceptance levels: remind of main checks Cavity status Needed documents If Level reached Al1 Cavity after mechanical fabrication Mechanical, RF, vacuum, visual documents Proceed to Level Two Al2 Cavity before He-tank integration Mechanical, RF, vacuum, Treatment documents (bulk BCP, annealing) Proceed to Level Three Al3 He-tank integration, Final BCP and surface treatments, assembly of accessories for the cold RF test He-tank integration and pressure tests (mechanical, RF, vacuum, visual documents, transfer measurements), last surface treatments, final vacuum and RF checks, outgoing inspection Integrated cavity ready to be cold RF tested Al4 Cavity cold RF tested Documents of the cold RF test, incoming/outgoing checks Cavity can be sent to CEA for string assembly Al5 Cavity accepted for string assembly Documents with incoming inspection at CEA Cavity final approval

The acceptance levels: where we are... Cavity status Needed documents If Level reached Al1 READY (subcomponents + M001 + M002) Al2 UNDER WORKING (M001 + M002) Al3 STILL TO BE TESTED Al4 UNDER WORKING NOW (P05 + MBLG002) Al5

General overview: docs The external Quality Control: documents 3 acceptance levels for the production at the cavity producer (Al1-Al3): Flow of documents/data: Subcomponents for the 1st six series cavities Al1: for M001 (completed), M002 (in progress) Al2: for M001 & M002 (in progress) for each cavity: #71 docs for subcomponents (mech.+3D+RF) #7 docs for Al1 (cav comp. + mech. + RF + leak check + inner/outer visual insp. + Al1 fullfillment) #32 docs foreseen for Al2 #44 docs foreseen for Al3

General overview: docs Subcomponents INFN-EZ exchange of instruction Cavity

General overview: docs The external Quality Control: documents 1 acceptance level for the qualification (cold VT) (Al4): Definition of documents/data under finalization: Al4: P05 & MBLG002 used for test Many interaction between INFN/DESY for measurements definition and incoming/outgoing procedures Cold VT of MBLG002 (no tank) done in July Cold VT of P05 (with tank) in those days #6 docs foreseen for Al4 RF (before delivery to DESY) RF (at DESY)

General overview: docs The external Quality Control: documents 1 acceptance level for cavity handover to ESS at CEA (Al5): Definition of documents/data under finalization: Al5: documents to be provided are under test and will be debugged soon (use of P05 + MBLG002 + M001 + M002) List of possible documents (a collection from previous Als): Mechanical measurements of the dressed cavity (with Tank) Transfer measurements Pressure test + Leak Checks after He-Tank integration FF after He-tank integration Reference frequency of the cavity after Final BCP (horizontal, air, no brakets) Leak check and vacuum quality Incoming inspection at DESY/outgoing inspection at DESY VT results (cavity performance) RF spectrum (horizontal, in vacuum, before delivery to CEA) List of parts in circulation (to be sent to INFN) INFN Certificate of conformity (cavity production + cavity test) NCR relative to interfaces (if occurred)

General overview: ESS_LASA_DMS & DataBase The external Quality Control: ESS-LASA-DMS Fruitfull collaboration with Brightness team (LNS) Alfresco used for managing of documents: EZ InBox -> used for document loading -> OK (subcomponents/Al1) Documents automatically sent to INFN experts for analysis and approval/rejection cycle (all Als) -> OK (subcomponents), under construction for Als EZ OutBox -> used for official communication from INFN to EZ (DumbBell composition, trimming instruction, cavity composition) -> OK NCR cycle out from Alfresco (RT system) -> only stored once solved -> under construction Ancillaries and other info -> under construction DESY OutBox/DESY InBox -> used for loading: Al3 docs (needed by DESY) & Al4 docs (DESY measurements) -> under construction ESS OutBox -> used for loading: Al5 docs -> under construction ESS InBox -> used for ESS final acceptance tests and cavity handover -> under construction

General overview: ESS_LASA_DMS & DataBase The external Quality Control: ESS-LASA-DMS The ESS-INFN (LASA) Dashboard: Simple and fast overview of documents status (loading/document status -> accepted/rejected) -> OK (subcomponents), under construction for Al1÷Al5 levels Inner Dumbbell before trimming Still to be approved by INFN Approved by INFN Rejected IC Inner Cells The ESS-INFN (LASA) Dashboard

General overview: ESS_LASA_DMS & DataBase The external Quality Control: ESS-LASA-DMS The ESS Dashboard: Data extraction for fast analysis of key parameters (plots, statistics); useful tool for prompt feedback to Industry -> OK (subcomponents), under construction for Al1÷Al5 levels More implementation will come with the running production Iris diameters is increasing -> prompt feedback to EZ for recovery action!
