Final manufacturing steps of Europe's Toroidal Field coils for ITER perfomed at SIMIC (IT).

in the core of the Sun every second 600 million tons of hydrogen are transformed into 595 million five hundred thousand tons of helium plus the extraordinary amount of power equal to five million years of reduction of the total energy produced by men on earth we are now pushing mankind's technology to reproduce such extraordinary fusion reaction on the heart inside a machine the toroidal field coils can be described as the magnets of all magnets that will operate in the ether machine these are the ones that will confine the superhot plasma within their powerful magnetic field they are among the largest components of the itter machine the TF coil manufacturing starts with a receipt of the large super conductive magnets called a winding pack weighing one hundred and twenty tons and measuring 9 by 16 meters a full dimensional inspection is performed by the most advanced technologies DC and AC electrical tests and a pressure test of the cooling channel art of formed before moving the winding pack in a large facking vessel for testing the lead test at 30 bar is done before starting the cooldown for testing the magnet in cryogenic conditions the TF quois armor is composed of four giant stainless steel parts called coil cases the coil cases are placed in a temperature-controlled area for testing a full dimensional inspection is performed by laser tracker scanning and photogrammetry the cooling circuits are be tested by helium and pressurised a 30 bar once the tests are over taken the insertion process can start two very large and complex machines were designed and manufactured by cynic over 1200 tons of concrete and 650 tons of steel were stacked to withstand the loads of the TF coils 72 axis fully electrically managed move the heavy TF coils with an impressive accuracy of 0.1 millimeter the winding pack is kept in a position by special g10 sliding pads machined by reverse engineering the coil cases are placed on their moveable lifters and slowly approach together to hoist inside the winding pack experts constantly monitor the positions the forces and the torques on each component to guarantee a perfect fitting between coil cases and the winding path the assembly rig is the key machine for the TF coils the nation of manual and robotized hardwired narrow gap ting technologies are carried out to complete over 80 meters of welding with a thickness of up to 125 millimeters with welding processes qualified at 4k and inspected by sophisticated ut phased array pushed to the limits of the psychic welding deformations are constantly monitored by laser tracker and photogrammetry the gap between the winding panic and the coil cases is filled by special resin the final machining of the TF coil is done by one of the largest milling machines installed in Europe the machine is installed in a temperature controlled area special machining heads have been designed on purpose to allow machining of the TF coiours with tolerances on the amplitude of sense of millimeters both sides of the TF coils have to be machined and a flipping of the TF coil is perceived in the middle of cycle the turnover of the TF coil is an impressive operation done by moveable liquors with a lifting capacity of over 600 tonnes the TF coil is then ready for final testing before shipping to the inter site [Music] once you shave all the tests are carried out for the last time full dimensional inspection electrical tests pressure and lead tests of the cooling circuits after one month the TF coil reaches site and it is ready for the final installation in the inner machine [Music] [Music]
