KAGRA Filter Cavity Kick-off meeting
Date/Time/Location
2021 Jan. 20th from 10AM
Connection: KAGRA Zoom2
Abstract
This is a project to install a filter cavity into KAGRA. It is not funded yet, but we should start preliminary design studies to prepare for the time when a fund is available. This meeting's purpose is to gather interested people and identify potential tasks to start this project.
Minutes
- Identification of Tasks
- Clarify the constraints
- Check available space, location
- Tomaru-san started investigation with Araki-san
- Near IYA, air ducts may interfere
- Using X-arm is also an option to consider
- Beam height choice (same as the main beam or lower)
- Tomaru-san started investigation with Araki-san
- Vacuum interface
- Check available flanges on OMC or OMMT chambers
- Can we penetrate the X-arm duct ?
- Cryostat door interference if we use the same beam height as the main beam
- Put GVs to make a removable section next to cryostats ? : risk of vacuum leak.
- Vacuum modifications in conjunction with overall KAGRA vacuum upgrade ?
- Check available space, location
- Conceptual design
- Filter Cavity Optical Design
- Squeezer design
- Doubly resonant OPO
- In-vac OPO ?
