In order to enable an iCal export link, your account needs to have an API key created. This key enables other applications to access data from within Indico even when you are neither using nor logged into the Indico system yourself with the link provided. Once created, you can manage your key at any time by going to 'My Profile' and looking under the tab entitled 'HTTP API'. Further information about HTTP API keys can be found in the Indico documentation.
Additionally to having an API key associated with your account, exporting private event information requires the usage of a persistent signature. This enables API URLs which do not expire after a few minutes so while the setting is active, anyone in possession of the link provided can access the information. Due to this, it is extremely important that you keep these links private and for your use only. If you think someone else may have acquired access to a link using this key in the future, you must immediately create a new key pair on the 'My Profile' page under the 'HTTP API' and update the iCalendar links afterwards.

ICFA Mini Workshop on High Order Modes in Superconducting Cavities
Fermi National Accelerator Laboratory
P.O. Box 500
Batavia, IL 60510-5011
(Mr), Vyacheslav Yakovlev
The objective of this workshop is to bring together researchers studying high order mode (HOM) suppression in superconducting cavities in the fields ranging from energy recovery linacs, light sources and linear collider applications. HOMs excited by beam in superconducting cavities can create excessive heat load on the cryogenic system and dilute beam quality, giving rise to a beam break up instability in the worst case. The workshop will discuss the current status of both experimental and theoretical work in this area. Issues in electron and proton linacs, Tesla style cavities, 3d harmonic cavities, TEM crabbing and other cavity designs will be considered. Current experiments at Fermilab, JLab, ORNL, Cornell University, and FLASH will be reviewed.
Workshop Working groups (conveners):
- HOM damping requirement (J. Sekutowicz, N. Solyak)
- HOM-based diagnostics (N. Baboi, R. Jones)
- RF simulation and beam dynamics (M. Liepe, O. Napoly)
- HOM damping couplers and loads (J. Delayen, T. Khabiboulline)
- Low level RF, controls and system integration (B. Chase, L. Doolittle)
