Strand dissipation distribution at quench in the cross section of PFIS W where the strand peak power generation is located for 13.5 kA at 6 T background field.
Strand dissipation distribution at quench in the cross section of PFIS W where the strand peak power generation is located for 41.5 kA at 6 T background field.
Vector plot of the self-field over the cross section of a PFIS leg (left) and SULTAN background field axial profile (right). The self-field in the centre of the CICC is not zero due to the second leg of the U-shaped sample carrying an opposing current. The self-field is higher at the surface of cable due to the assumption of uniform current distribution over the cross section. At the inner edge (x ∼ 18 mm) self and background field sum, while they subtract at the outer edge (x ∼ −18 mm).The insert shows one leg of the PFIS sample with the used system of reference.
