[Luke, Luis, Tyler, Ma, Christina, Maple]

We started by cleaning outside of the cleanroom wiping down the cable channel and working our way down. We replaced the air filter in the HEPA filter with what seemed to be the last one in storage. We then vacuumed outside, before wiping down the inside of the cleanroom. We then vacuumed, mopped, and wiped down the floor inside the cleanroom.

We are ready for venting the vacuum chamber which is planned to take place 6/26/25 at 10am.
