TAN situation • 4 TANs are installed in IP1L&R, IP5L&R• Each TAN is equipped with 1 slot corresponding to 10 Copper bars• TANs are situated in LSS zones with ~0,7 degree slope and 0,4 degrees tilt• Overall measured dimension of the slot is 998x94,9x605mm (lxwxh) (inf. to
design)• Tilt combined with height of the slot (605mm) gives an horizontal shift of 7,5mm
in parallel to the machine axis and ~4mm perpendicular to this
