The system manufactured, shipped and installed by NTG consists of 22 mirror chambers mounted on a steel rack or granite block, optical tables (breadboards) for each chamber which are mechanically decoupled and independently adjustable in height, 103m of DN500 pipe, various vacuum slides, steel racks, pipe supports, granite blocks and a complete vacuum system.
The challenge in this project was to deliver components that were very clean and low in particles. All components coming into contact with the vacuum were electropolished and thoroughly cleaned under clean room conditions to avoid hydrocarbon residues, contamination and particles on the surface.
The assembly of the vacuum components took place in sections under ISO5 conditions.
