FCC-FS EPOL group and FCCIS WP2.5 meeting 17

Thursday 9 Feb 2023, 13:30 → 15:30 Europe/Zurich

The FCC technical and financial feasibility study comprises a work package (EPOL) on precision determination of the centre of mass energy at FCCee. using resonant depolarisation of the beams, in conjunction with precise measurement of the energy spread and other parameters using physics events in the detectors, and other beam diagnostics in particular to control the collision parameters. Specific equipment involves polarimeters for both beams, polarisation wigglers, and depolarising RF kickers. The possible mono-chromatization of the beams in view of a measurement of the e+ e- —> H (125) process will also be studied and special requirements investigated. 

Short group meetings are foreseen at 16:30 on Thursday typically every two weeks. 

13:30 → 13:40 Introduction and general news

Speakers: Alain Blondel (Universite de Geneve (CH)), Guy Wilkinson (University of Oxford (GB)), Jacqueline Keintzel (CERN)

13:40 → 13:50 Polarization at KARA
