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.

Higher Order Mode Measurements in Superconducting Accelerating Cavities
Bldg. 24, Rm 200 (DESY, Hamburg)
Bldg. 24, Rm 200
Higher Order Modes (HOM) and wakefields are a major common concern for the beam dynamics in superconducting accelerators. At the TTF/FLASH facility at DESY in Hamburg, various measurements have been carried out during time, for the study of the HOMs, but also on their use for diagnostics. Some of the first measurements used an intensity-modulated beam to find single high impedance modes from the spectrum. The most recent measurements deal with using the HOM signals as beam position monitors. In an attempt to match future measurements to the requirements of various projects, such as the XFEL and the ILC, but also other projects using superconducting technology, this mini-workshop on HOM measurements in superconducting cavities is held. The tentative agenda is as follows:
- review past measurements
- review important HOM-related questions for the beam dynamics in superconducting accelerators (particularly ILC, XFEL),
- present ideas for possible future measurements
- review facilities where such measurements could possibly be carried out in the future, in addition to FLASH
