Thermal compensation system for the 40m arm cavity

Goal

To compensate for imperfections that arise due to optical inhomogeneities in the arm cavity mirrors by designing and implementing a thermal compensation system. The lessons learned from this exercise will help with designing/implementing a similar kind of system for the folding mirrors in the power recycling cavity.

Things to be looked into

What are the ideal cavity parameters?

Thermal effects due to circulating arm cavity power

HOM degeneracy

Increase or decrease RoC of the ETM to correct for inhomogeneities (also by how much)
