* 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 ''&phi;'') of the magnetic field, mounted in a 0.5 mm thick stainless steel tube attached to a port flange. They are located in [[TJ-II:Sectors|sectors]] B5 and C4, at ''&phi;'' = 142 and 218 degrees.
