Modeling Virgo with Finesse3

This workshop will gather members of the Virgo and Finesse teams at Nikhef for a focused, collaborative week of interferometer modeling using Finesse 3. Which is the latest release of the interferometer simulation software developed for precision modeling of optical systems:

The core goals of the workshop are to:

• Advance modeling studies that address current challenges in the O4 configuration, particularly those relevant to commissioning and sensitivity limitations.
• Support ongoing design and simulation work for the O5 configuration, including investigations into optical layout changes and control strategies.
• Enable hands-on collaboration across institutions and expertise levels, fostering shared development of models, debugging, and interpretation of simulation results.
• Facilitate knowledge transfer and training for new users and contributors to Finesse3.

The workshop schedule will be flexible to accommodate the needs of participants. Each day will include optional group check-ins and brief technical presentations to share progress and ideas. Outside of these sessions, participants are encouraged to work independently, with help from the local Finesse team, or in small groups on modeling tasks that are most relevant to their current projects.
