13. 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

14. 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

15. 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!
