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.

Time-resolved X-ray diffraction studies of non-equilibrium solidification in deeply undercooled melts
Solidification of virtually any substance is initiated by nucleation and growth of the solid phase at the temperature below the equilibrium liquids. In particular, for metallic alloys the difference between liquidus and nucleation temperatures, called undercooling, varies from incrementally small up to hundreds degrees of Kelvin. While conventional casting does not typically involve large undercooling of the melt prior to solidification, other production routs, e.g. gas atomization, additive manufacturing, etc., are inherently prone to it. Both retarded nucleation and rapid heat transport lead to acceleration of the solidification process such that no time remains to establish equilibrium conditions at the solid-liquid interface. Moreover, below the equilibrium, liquidus nucleation of the other solid phases can become thermodynamically and kinetically viable. It is this rapid non-equilibrium solidification that produces remarkably different microstructures and results in modified material properties. Due to fine length and short time scales of the event, its study requires non-trivial techniques. Here we discuss the possibilities to access the deep undercooling and in situ determination of subsequent solidification processes in industrially relevant systems by combination of the electromagnetic levitation technique with the time-resolved X-ray diffraction of synchrotron radiation. Experiments conducted at the high-energy materials science beamline P07 of Deutsches Elektronen-Synchrotron (DESY) allowed for the first time to determine the structure of the metastable phases, found in studied systems.
