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.

X- and gamma-ray polarimetry in future space missions
Rui Curado da Silva
By measuring the polarization angle and the degree of polarization of celestial emissions, it will be possible to increase the number of observational parameters, thereby allowing better discrimination between various models characterizing the same object. Polarimetric observations can provide important information about geometries, magnetic fields, composition and emission mechanisms in a wide variety of gamma-ray sources, e.g. Pulsars, Solar Flares, Active Galactic Nuclei, Galactic Black Holes or Gamma-Ray Bursts.
So far, no dedicated gamma-ray polarimeters have ever been launched into space.
DUAL and GRI (Gamma-Ray Imager) mission proposals to ESA Cosmic Vision programme are among the few missions that include high energy polarimetric observations. Our group has been developing this kind of instruments for more than a decade, optimizing focal plane instrumentation both by Monte Carlo simulation and by prototype testing.
