Description

The aims of the meeting are to:

Identify all requirements for a fully working demonstrator instrument in the LHC tunnel by March 2020 (V3)
Identify “must haves” installation for LS2,
Summarise the know-how gained at Cockcroft, GSI and with the LHC fluorescence experiment. Identify the open issues with this knowledge gained with the aim of an operational instrument in LS2.
Review the administration progress (Planning, ECR done and in progress, Infrastructure requests, project founding, responsibility share boundaries)
Up-date on the status, requirements and compatibility with the HEL of the LS3 BGC (V4)
Agree on an experimental programme on the Crockcroft 2 test bench (V2) for 2019
Review the status and compatibility with the HEL of the LS3 BGC (V4)
Gas type: Neon is baseline. Summarise reasons for that choice. What were the impacts if change to Nitrogen or Argon.
Evaluate realistic goals for the performance concerning precision and resolution
Arguments to keep and modify the fluorescence test set-up for Run 3
