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 most convenient and efficient way to obtain a beam for a fixed target experiment from the LHC is, to our knowledge, to use bent-crystal beam extraction. The idea is therefore to position a bent crystal in the halo of the beam such that a few protons (or lead) per bunch per pass would be channelled in the lattice of the crystal and would be deviated by a couple of mrad w.r.t. to the axis of the beam. Such a method also has the virtue of better collimating the beam, allowing one to increase the luminosity of the collider experiments. Tests of this technique will soon be carried out by the LUA9 collaboration following the recommandation of the LHCC.
During this meeting, we will discuss:
the status of bent-crystal beam collimation and extraction
the status of future test at the LHC by LUA9
the physics opportunities offered by a fixed target experiment on the LHC beams extracted by a bent crystal (AFTER@LHC)
the possible synergies between LUA9 and AFTER, as well as between LAL and IPNO in this context.
