* Two straight arrays above the plasma column, each with 12 coils, distributed in 4 groups of 3 coils each, separated by a distance of 30 mm. The three coils in each group measure the three cylindrical components (''R'', ''Z'', and ''φ'') of the magnetic field | * Two straight arrays above the plasma column, each with 12 coils, mounted in a 0.5 mm thick stainless steel tube attached to a port flange. The 12 coils are distributed in 4 groups of 3 coils each, separated by a distance of 30 mm. The three coils in each group measure the three cylindrical components (''R'', ''Z'', and ''φ'') of the magnetic field. They are located in [[TJ-II:Sectors|sectors]] B5 and C4, at ''φ'' = 142 and 218 degrees. | ||
