Magnet ID : YAAT01 Vacuum vessel length 54.84 inches 139.3 cm Moly 2.44 mm (0.096") max. min beam sep ~10 mm WR3 WG used as conductor. Hole size: inches(mm) 0.034 [0.8636] 0.017 [0.4318] Scaling the drawing, since I can't find a WG vendor with outside dimensions, I deduce 0.020" wall thickness and 0.002" corner radius. 0.001" corner radius inside hole. Overall area 4.2054E-3 sq in. Hole area 0.5749E-3 sq in Copper area 3.6306E-3 sq in 2.3423 mm^2. At 70 A, J = 30 A/mm^2. Need double that to double energy. Insulated 5 turn coil pack: 0.07" by 0.47" Core length 100 cm Insulated coil pack sticks out 0.5" on either side of core before individual pieces of WG are separated for water circuits and connection to big conductor on back leg. Backleg coil has five turns of 0.188" square with 0.125" diameter hole, except each end has a 0.125" OD 0.020" wall tube brazed in for water connection. Assume just the square section: 23.07E-3 sq in or 14.885 mm^2. Only 4.7 A/mm^2 here. Water cooling still needed, barely. Doubling this J not a problem with our LCW. Meas. # : GENERIC Meas.
