BGC Collaboration Meeting at CERN
→
Europe/Zurich
CERN
CERN
Description
The aims of the meeting are to:
- For the V2 instrument in Cockcroft: Summarise the measurements of 2019 and define the measurement priorities for 2020
- For the V3 instrument LHC tunnel installation: Give the status on the tunnel installation and V3 instrument design
- For the HEL test stand with V3 design: Define the objectives of the tests, what can be the expected performance, define work share on the HEL test stand with BGC V3 and planning
- HLLHC instrument: Identify design limits with integration constraints, optimise gas jet creation and choice of gas, expected performance, view of schedule and tasks
- Review status of the collaboration, publications, manpower and budget planning
- Fluorescence tests in LHC with distributed gas: Review results and expectations with run 3.
- Discuss alternative gas jet generation.
