ECLOUD'22 and GWDVac’22 Workshops

25 Sept 2022, 17:00 → 1 Oct 2022, 09:00 Europe/Rome

Hotel Hermitage (Italy, La Biodola Bay, Isola d'Elba)

The ECLOUD’22 and the GWDVac’22 workshops will take place at Hotel Hermitage, La Biodola Bay, Isola d'Elba (Italy) from the 25th (arrival date) to the 1st of October (departure date) 2022 on site.

ECLOUD’22 will last 3 full days (from 26th to 28 September) and will be followed by the two-day Workshop GWDVac'22, the 29th and 30th September 2022, which is a workshop devoted to discuss Gravitational Wave Detectors Vacuum issues.

The 28th of September a joint afternoon will take place aiming to stimulate synergies between the two communities working on Particle Accelerators and on Gravitational Wave Detector Vacuum, respectively.
