Call for Abstracts

  • Opening day
  • Submission deadline

Participants are encouraged to submit abstracts on subjects of interest to the International High-power RF community. 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

Since 2008 we archive all workshop presentations and proceedings at one centralized place under the CERN Indico system. Please note in order to submit an abstract you need to have a CERN Indico account. In case you do not have it yet, create a CERN light-weight account, which will work well for the purpose.
After clicking "Submit new abstract" you will be directed to CERN Single Sign-On page. At the very bottom click "Create/Check your account", which will lead you to the Account management page. In the right column click "Register an account" and follow the process. Now you are good to submit an abstract.
In case of difficulties please contact

The call for abstracts is open
You can submit an abstract for reviewing.
