Detector Description Summer Workshop

30 Jun 2025, 09:00 → 4 Jul 2025, 17:00 Europe/Zurich

Salle des Presidents (Tour Lombarde (Conthey Switzerland))

ATLAS Detector Description Summer Workshop will take place at Tour Lombarde, Conthey, Switzerland, from June 30 to July 4, 2025. During the previoius workshop we put the new DD workflow into practice and implemented plans laid out in the "procedures & roles". 

Our goals for the summer workshop are to accelerate progress towards complete validation of the new DD workflow in Run 3 and to make progress towards its implementation on the context of Run 4. 

Please let us know if you will join us by filling out the registration form. If there are special discussions you think are necessary during the workshop, please bring them to the attention of the Detector Description group in advance.

A  registration fee of CHF 200 will be collected during the workshop (or CHF 40/day for shorter participation)
