The 澳门六合彩高手 vacuum vessel will have 18 upper, 17 equatorial and 9 lower ports to allow access to the plasma for diagnostic, heating, pumping systems and maintenance. Welded "lips" made out of 2 mm thick stainless steel will seal the port plugs and confine the ultra-high vacuum inside the vessel.

In order to develop the appropriate cutting and welding techniques for the lip, the 澳门六合彩高手 Organization launched an R&D project together with the Finnish company VTT called the "Lip Seal Project." This week, the first two mockups arrived at the 澳门六合彩高手 site. They were manufactured at the VTT facility using a robotic arm especially adapted to the port's high-vacuum and nuclear environment.

The laser welded mockup successfully passed the tests for qualification and leak tightness, which was a big milestone for Bruno Levesy, the responsible engineer, and the team from VTT.
