ACHTUNG! Indico Wartung mit Dienstunterbrechung am Donnerstag dem 16.12.2021 von 10:00 Uhr - 11:00 Uhr (CET). Bitte beenden Sie ihre Arbeit rechtzeitig um Datenverlusten vorzubeugen! ATTENTION! Indico Maintenance with downtime on Thu 16 Dec 2021, 10 - 11h CET. Please finish your work in time to prevent data loss!
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.

Status of superconducting undulator developments at the Advanced Photon Source
(Advanced Photon Source, Argonne National Laboratory)
XHQ / E1.173 (European XFEL)
XHQ / E1.173
Superconducting undulators (SCUs) have been under active development at the Advanced Photon Source (APS) in the last decade. Several SCUs, planar and helical, have been installed at the APS storage ring and are currently in operation. All these devices demonstrated high performance and reliability levels.
Currently all operational SCUs at the APS are NbTi- based devices. Recently, the new development of Nb3Sn undulators began. Several short, 10-period prototypes were designed, built, and tested. Their performance exceeded expectations and very closely approached the performance of a short wire sample. Based on the prototype design, the APS will build two new 1.2-m-long Nb3Sn undulators and install them in-line at Sector 1 of the APS storage ring.
The in-line double-undulator design is planned to be tested as a module prototype for future XFELs. The module will be equipped with quads, a phase shifter, and BPMs. Also, an advanced in-situ alignment system will be incorporated. The module will be tested first at the APS SCU magnet measurement laboratory. After that it will be considered for installation at the hard x-ray beamline of LCLS-II.
