The inside of the cavity was cleaned today. It was very dirty and had big dust particles and fibers inside.
Cleaning was done for everything; wall, floor, fixed mounts, wires (still have some dust difficult to remove), edges.
The dust meter average was measured outside the cavity (2471 p/m3 av 6 min) and inside after cleaning (1424 p/m3 av 10 min).
The cavity was left open under the clean air flow, will observe it under UV, clean and measure Dust tomorrow.
Images attached are after cleaning.
Objects inside the cavity at the moment :
- 4 main mirror mounts
- 4 mirror fixers on mounts and 3 screws each (total 12)
- 2 reflecting mirror mounts
- 2 dielectric mirrors (mounted and to be cleaned)
- two mounts for D-shaped mirrors.
- 2 D-shaped mirrors (unmounted, and they will need cleaning)
- 2 metal irises (pinholes)

The cleaning was done twice with half an hour interval between the two times
reading on the dust meter was taken after each time, and it was zero averaged over a 10-min

An Initial cleaning of the KBoX outside was done, All the optics and mechanics placed that were on the table were removed.
Only the old Mitylaser amplifier remains on the table.
Since we will be using the ThomX Celia amplifier, we will remove it and place it in a secure location (to be decided).
Tomorrow a cleaning of the inside of the cavity box is to be done.
