Powerheat’s pipe installations for the Cryo-Compressor Building (G04) and the CTL tunnel were near completion, including mounting of pipe support, welding and X-ray controls. The final pressure and leakage tests with Helium are now underway. In the Target area (D02) , the second of five vault castings for the Monolith was completed, while form and reinforcement work for the Active Cells area walls continues. Pressure tests for the entire Accelerator tunnel (G01) were completed and survey and alignment reference points for installation of the LINAC are being marked. In the Gallery Building (G02) there are now two Klystrons in the Test Stand area awaiting installation, and roof works are in progress. Substantial progress has also been made on the roof membrane for the sloped Green roof atop the Accelerator tunnel, with grass seeds expected to be planted in the autumn.
