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.

Protecting LHC IP1/IP5 components against radiation resulting from colliding beam interactions
Nikolai MOKHOV (FNAL)
SL Auditorium (CERN)
Beam-induced energy deposition in the LHC high luminosity interaction region (IR) components due to both pp-collisions and beam loss in the IR vicinity is a significant challenge for the design of the high luminosity insertions. In this talk the results of thorough optimization and comprehensive MARS calculations are summarized for the LHC lattice, version 6.4, for the updated IP1 and IP5 layouts and a baseline pp-collision source term. Power density, power dissipation, particle fluxes and spectra, accumulated dose and residual dose rates are studied in the components of the inner triplets including their TAS absorbers, the TAN neutral beam absorbers, separation dipoles, and quadrupoles of the outer triplets and possible collimators there. The current design is proved to provide the best safety margin under realistic engineering constraints.
