BGC Collaboration Meeting - ONLINE

10 Dec 2020, 13:00 → 11 Dec 2020, 17:55 Europe/Zurich

CERN

The aims of the meeting are to:

• For the Version 3 instrument: Give the status on the LHC tunnel installation, instrument design and procurement
• Define the Version 3 Phase 1 remaining LHC tunnel installations for 2021
• Version 3 Phase 2 manufacturing, quality control and assembly status update 
• Cockcroft Institute (CI): commissioning and performance evaluation plan for Version 3 Ph. 2
• For the HEL test stand with the BGC V3 design: Define the objectives of the tests (including gases and background light from the cathodes), that can be the expected performance, define work share and planning
• For the V4 instrument with performance defined from the acceptance criteria (EDMS: 2369616): give updates on design issues including gas jet generation and vacuum constraints in the HEL context
• Summary of experimental measurements performed and results from CI since March 2020
• CoVid 19 impact on BGC progress
• Review status of the collaboration, publications, manpower and budget planning
