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.

In recent years parton distributions, describing longitudinal momentum, helicity and transversity distributions of quarks and gluons, have been generalized to account also for transverse degrees of freedom. Two new sets of more general distributions, Transverse Momentum Dependent (TMD) parton distributions and Generalized Parton Distributions (GPDs) were introduced to describe transverse momentum and space distributions of partons. Great progress has been made since then in measurements of different Single Spin Asymmetries (SSAs) in semi-inclusive and hard exclusive processes providing access to TMDs and GPDs respectively. Different facilities world-wide including HERMES at HERA, CLAS and Hall-A at JLab and COMPASS at CERN have measurements of TMDs and GPDs as one of their main focuses of research.
Kaon identification provides important additional information about the sea structure in general and spin-orbit correlations in particular. Recent measurements of SSAs at HERMES with charged Kaons indicate that current understanding of the nuclear structure in terms of partonic degrees of freedom is incomplete and more data is needed to resolve the so called “Kaon puzzle”.
Studies of GPDs and TMDs are also one of the main driving forces of the JLab 12 GeV upgrade project. In this talk we present a possible upgrade of the CLAS12 detector at JLab to make Kaon identification available over the full momentum range and the new physics accessible with the CLAS12-RICH detector.
