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.

Visualizing ultrafast dynamics with femtosecond X-ray pulses

Free-electron lasers are a new class of X-ray sources that deliver extremely intense, coherent x-ray flashes with femtosecond and in the future even attosecond pulse length. The unprecedented brightness of these X-ray lasers opens the door for imaging transient states of matter and non-linear X-ray spectroscopy approaches involving core-level states. I will present selected recent experiments in two areas. First, I will present opportunities in AMO and nanoscale physics arising from ultrafast imaging approaches. Single-shot imaging of individual superfluid helium nanodroplets allows the unambiguous identification of quantum vortices. Ultrafast scattering of highly excited nanoplasmas carries information about their transient electronic states. The combination of optical with X-ray lasers as well as X-ray pump/ X-ray probe schemes allow the investigation of dynamically evolving systems with femtosecond time and nanometer spatial resolution. I will finish my talk with current developments on multi-color and time-resolved X-ray spectroscopy approaches that are opening the door for visualizing electron dynamics and understanding the complex interplay between ultrafast electronic excitations and nuclear response in molecular systems.
