| Disassemble IVC. Removed IVC bottom, IVC middle, 100 mK can lower, IVC top. Cleaned IVC flanges. | |
| Removed improvised foil baffle from stripline tube. Baffle and tape were intact. | |
| Some tape had come loose from the bottom covering of the 100 mK can. | |
| Removed stripline tube by loosening o-ring connections at top of fridge. This proved difficult - the rings at the top were very tight and the tube was stuck. Used a large D-clamp to grip the upper ring. These top connections have been leaky as seen during spray leak checks. We intend to replace the o-rings before reassembly. |
