Seventh vertical coil reaches ITER

Seven toroidal field coils have reached ITER in the past year. The latest, TF3 from Europe, passed through the ITER gates on Friday 3 May.
Toroidal field coil #3 (TF3) travels the last leg of the voyage to ITER early on Friday 3 May 2021.
The European and Japanese Domestic Agencies are sharing the responsibility for the procurement of 19 toroidal field coils (18 for the machine, plus one spare).

Since the first coil arrived on site in April 2020, a total of seven have been received, and another five are expected before the end of the year.

Toroidal field coils will be associated by pair with each vacuum vessel sector. Coils TF12 and TF13, from Japan, will be the first to be mounted on specialized tooling in the Assembly Hall. TF3, the most recent arrival, will join others in storage, where assembly contractors will use the opportunity to advance mechanical preparatory activities such as welding cooling pipes, attaching clamps, and welding interfaces prior to assembly.
