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.

White Rabbit (WR) is an innovative technology that provides sub-nanosecond accuracy and tens-of-picoseconds precision of synchronisation as well as deterministic and reliable data delivery for large distributed systems. This presentation will illustrate the key features of WR by describing three such systems: BTrain over WR, WR trigger Distribution and Radio Frequency Signal Distribution over White Rabbit (RFoWR).
The BTrain system ensures synchronism between the ramping up of the bending magnetic field in the accelerators and the gain in momentum of the accelerated particles. It broadcasts the measured value of magnetic field in real-time to the RF accelerating cavities, instrumentation and power converters. This system has been upgraded to use WR, and constitutes an example of deterministic data transfer inside a real-time feedback system. The presentation will explain the architecture and basics of operation of the upgraded BTrain over WR.
The White Rabbit Trigger distribution (WRTD) project leverages WR and augments it with complex trigger event scheduling, in order to virtually negate the distances between event sources and receivers. This presentation will introduce the audience to WRTD and provide hands-on examples of using the provided API to configure and distribute events over WR.
The RFoWR system combines WR with Direct Digital Synthesis technology to distribute RF signals. A number of RFoWR systems have been and are being developed at CERN. We look at their performance and features. In particular, a new WR2RF card that will be a key component of the new SPS RF system to drive Bunch and Turn clocks for the TTC network on which the Beam-Synchronous Timing (BST) system is based.
