Abstract
The stray magnetic fields produced at plasma initiation (in particular at the gas breakdown (BD)) by the ITER tokamak complex building have been studied. The influence of global elements of the tokamak complex building is estimated. The scenario of plasma initiation was designed and simulated using virtual coils with currents producing a magnetic field in the BD region similar to that from the building.
