Working Groups

The list of working groups and their charges is shown below. If you would like to contribute a presentation, please contact the WG conveners

WG-1: Challenges of Global Collaboration

Conveners: Christian Boffo / FNAL, Yasuchika Yamamoto ('Kirk') / KEK, Nicolas Bazin / CEA

Several SRF projects or upgrades either in progress or in planning have significant content that is being supplied from national or international partners. WG1 is focused on the challenges of SRF collaborations involving multi-institutional deliverables. The discussions would include such topics as safe transport of equipment, best practice in facilitating communication/documentation/engineering across multi-institute projects, qualification of designs/equipment involving engineering codes across national boundaries and the harmonization of safety regulations such as the high-pressure gas code. The scope of WG1 is to offer a forum for a discussion of various aspects of multi-institution and multi-national collaborations.

WG-2: Progress on high Q and high gradient

Conveners: Daniel Bafia / FNAL, Jinfang Chen / SARI, Akira Miyazaki / Uppsala Univ. & CERN

The scope of this working group is to discuss the most recent results related to pushing Niobium towards higher Q and higher gradient and progress in thin films research. For niobium, advances in understanding material evolution under established but also newly developed heat treatments, such as N-Infusion, N-Doping, Low-T Bake and Mid-T Bake, the differences and advantages of low-temperature EP compared with conventional EP, and current results on flux-expulsion studies should be discussed. The presentations and discussion should include results from both elliptical and TEM mode cavities. The interplay between theoretical approaches and experiments should be emphasized. Results from sample and cavity studies (different cavity types and frequencies) which could help to establish a core understanding should be included. Finally, new results from alternative materials like Nb3Sn, thin films and multilayers and, in particular, a summary report from the thin film working group should also be presented and discussed.
