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.

The LUXE Experiment in Hamburg: probing quantum physics in a new regime
(UC Berkeley and Lawrence Berkeley National Lab)
This talk describes LUXE (Laser Und XFEL Experiment), an experiment that aims to use the high-quality and high-energy electron beam of the European XFEL and a powerful laser. The scientific objective of the experiment is to study quantum electrodynamics in the regime of strong fields, close to and beyond the Schwinger critical field. Within a strong electromagnetic field, the vacuum itself is expected to become unstable and spark with spontaneous creation of electron-positron pairs. This experimentally new regime is relevant to a variety of phenomena in Nature, e.g. in the areas of astrophysics, collider physics or atomic physics. It is anticipated that the LUXE experiment electrons accelerated by the European XFEL Linac shall experience a field three times larger than the critical field, and pioneer this regime of quantum physics. In this talk the science case and the experimental setup are described. The setup requires in particular the extraction of a minute fraction of the electron bunches from the European XFEL Linac, the installation of a powerful laser with sophisticated diagnostics, and an array of precision detectors optimized to measure electrons, positrons and photons.
