An object with a shine to its underbelly

From this angle, the object seems shaped like a mushroom cap. In reality, this lid segment of the large cryostat that recently arrived on site is oblong in shape—nearly twice as long (22 metres) as it is wide (almost 11 metres). 

When it arrived at ITER, the cold chamber for the magnet cold test facility at ITER was wrapped in white plastic. Upon delivery to its final destination in the former winding facility for poloidal field magnets, it was unpacked and separated in two—the deep chamber positioned just inside the wide doors of the building that will open to admit the first toroidal field coil to be tested at 4 K (minus 269 °C); the top lid, with its undercoating of shiny silver insulation (photo), positioned on temporary supports a few dozen metres to the side.

We'll have a full report about magnet test bench commissioning in an upcoming edition of the ITER Newsline.
