23 July 2018

The last two weeks on the construction site brought advances in Accelerator installation and civil construction of the Target Station and instrument halls.

Several concrete castings moved the construction forward throughout the Target area (D02). New castings have been made at the Monolith walls, accelerator-to-target area, active cells utility, transport and technical gallery areas, and the adjacent D01 and D03 instrument halls. Construction of the Monolith’s high-bay vault has now begun, while casting of the active cells waste pits is completed and procurement of their shielding lids can begin.

The first several metres of the Accelerator tunnel (G01) are beginning to fill up. Technical installations have moved rapidly forward in both levels of the Front End Building, including the infrastructure and support systems for the ion source and low-energy beam transport line (LEBT) installed at the front of the tunnel. Commissioning is scheduled to begin in September.

The radio frequency (RF) waveguide system, a British in-kind contribution, is also on the verge of installation, with the heavy steel support structure installations in the klystron gallery (G02) nearly complete. The first waveguide units themselves have been delivered and are awaiting installation in the Stubs linking the gallery to the tunnel.

The accelerator’s Test Stand 2 (TS2), for cryomodule testing, continues to move toward commissioning as well. The cryo-chicane shielding bunker has been cast and formwork removed, while the cryosystems piping is being installed between the Coldbox and the test stand.

Meanwhile, interior works continue throughout the E-buildings.
