Submission deadline
Participants are encouraged to submit abstracts on subjects of interest to the International High-power RF community. CWRF is an informal workshop where experts discuss, therefore contribution does not require submission of a scientific paper.
Submission requires log-in to the CERN Indico system. If you do not have an account yet, please follow the instructions to create a CERN lightweight account. In case additional support is needed, please contact daniel.valuch@cern.ch.
Areas typically covered at the CWRF workshops are:
High Power RF System Status and Operating Experience
- Facility status reports on upgrades, performance, and reliability
- High-power component testing/conditioning processes and results
