Nov 14, 2023, 6:00 AM → Nov 17, 2023, 8:00 PM Europe/Paris

200/0-Auditorium - Auditorium P. Lehmann (IJCLab)

Einstein Telescope Annual Meeting: Nov. 14, 2023 -- Nov. 16, 2023

The 2nd Einstein Telescope Annual Meeting will be the opportunity to discuss key points of the ET collaboration and of the ET design.

The meeting is hosted by the “Gravitational waves” group of the Astroparticles, Astrophysics and Cosmology (A2C) department of the Irène Joliot-Curie Laboratoire des deux infinis (IJCLab). It will take place in the IJCLab Lehmann auditorium (building 200) in the campus of the Paris-Saclay University. Open to all ET collaboration members, it will start on Tuesday morning November 14th and end on Thursday November 16th at lunch time. In-person and remote registrations are possible.

Sustainability workshop: Nov. 16, 2023 -- Nov. 17. 2023

Immediately following the ET Annual Meeting, there will be a Sustainability Workshop (Thu. afternoon 11/16 and Fri. morning 11/17) organized in collaboration with the ET Preparatory Phase Project. Registration is free for this workshop and can be done either through the registration to the ET Annual meeting, or separately for the persons planning to only attend that workshop.

The idea is:

to have 3 short introductory presentations, one by each division, summarizing the main requirements and the design status on an adequate flight level,
followed by 1 hour of discussion.

The objectives are:

to collect and understand the different constraints and concepts 
to start discussions of how they may be integrated.
