Mockup pre-compression rings, one-fifth ITER size, are manufactured at ENEA in Frascati, Italy following vacuum pressure impregnation techniques. Mockup rings are stressed to rupture in a testing machine (pictured), which presents 18 hydraulic independent pulling holders providing a stress distribution in the rings similar to the one the 18 toroidal field coils will induce during operation.

Japanese qualification prototype of ITER's divertor vertical target successfully passes high heat flux performance tests in the electron beam facility "Tsefey-M" located at the Efremov Institute in St. Petersburg. The outer vertical target of the ITER divertor consists of a lower straight element covered with carbon monoblocks, an upper curved element with tungsten monoblocks, and a steel support structure.

The poloidal field insert coil is made from a 40m length of conductor for the ITER poloidal field coils. The conductor is made of 1,400 NbTi strands in what is called a cable-in-conduit configuration. The conductor is successfully taken up to an operating point of 52kA at 6.5T and 4.6K. Pictured: the vacuum vessel and busbars connected to the current leads at the test facility.

On 11 March 2008 a team from Oak Ridge National Laboratory (ORNL, US) successfully produces the first deuterium ice using a twin-screw extruder. This new prototype extruder is 1/5 the size of the device that will be required for ITER, which will be capable of injecting an infinite number of pellets into the ITER plasma. It is the first step towards a pellet injector feeding particles deep inside the plasma.

This real-size divertor cassette is used on the Cassette Multifunctional Mover (CMM) at VTT's Divertor Test Platform in Finland. Because of the enormous loads involved, the need for a high degree of positional accuracy and the minimal operating space within the ITER tokamak, the CMM demonstrator takes advantage of water hydraulics technology and virtual reality techniques to practice the manoeuvring of ITER divertor cassettes.
