Anti e-Cloud Coatings - "AEC'09"

12 Oct 2009, 08:00 → 13 Oct 2009, 20:00 Europe/Zurich

CERN

Elena Shaposhnikova (CERN), Frank Zimmermann (AB/ABP), Mauro Taborelli (CERN)

Topical workshop on anti e-cloud coatings that do not require activation The goals are to exchange experience with production, characterization, accelerator implementation & beam performance, and to review the present performance and future plans for coatings at the various laboratories. Workshop topics will include : (1) motivation and requirements on coatings (secondary emission yields etc), (2) future plans, (3) production and characterization of coatings, (4) vacuum and impedance properties, (5) beam measurements with & w/o coatings

Monday 12 October

Motivation, e-cloud Beam Observations & Simulations, Coating requirements
