Design and construction of an eight Tesla insert coil

Experimental and numerical results on transient heat transfer to supercritical helium at low temperatures

“…A detailed description of the loop is given in ealier reports [3,4]. The test section was made of a rectangular OHFC copper tube, which also has been used in the Sultan 8 T inner coil [7]. The tube had a length of 174 mm and it had been soldered between two 90 ~ bends of stainless steel (soldered length of copper in each bend was 9.7 ram).…”
