+After [[TJ-II:Construction|construction]] of [[TJ-II]] was completed, the accuracy of the magnetic field was checked by measuring the vacuum flux surface mapping and comparing to theoretical predictions.
+The mapping was done at a magnetic field strength of 10% of the nominal value.
+The detection process involved imaging the spots produced by electrons, produced by an electron gun, when these intersect an array of fluorescent rods that sweeps the vacuum vessel cross section.
