I made a thermal insulation box for the cell holder that will be used in iodine setupr, see ATF:1665. I used the similar style to CTN refcav insulation. We can make more space in the foam to hold more thermal sensors later. I'll see if I can test how good it can stabilize the temperature tomorrow.
Plus, I also made another thermal insulation for an EOM. It is based on what frank did inPSL:744. It can be used for Gyro or for CTN lab when I have to install two lasers later.
