Describe LCGT/subgroup/ifo/ISC/TaskList/SpatialMode/SpatialModeDesign here.

Preliminary (base) desisn of folded stable cavities

The task is to determine the locations and the ROCs of the folding mirrors given the following constraints.

Boundary Conditions

The boundary conditions for the design of the folded RCs are the following.

Design of folded stable cavities

Design of unfolded stable cavities

Current design of marginally stable cavities

Some limitations in the view of vacuum and seismic attenuation group

Higher order mode check

Higher order modes of the arm cavities should not overlap with sidebands and their harmonics.

This was checked here.

Old (current) layout of vacuum tanks
