The conductor tested the wheel assembly with a hand-held heat detector called a Tempilstik, but he apparently applied the device to the wrong part of the wheel assembly, officials said last week after a re-enactment of the accident.
In this project, conductor tests for four types of coil conductor and joint tests for seven types of conductor joint have been conducted for the past eight years using the NIFS test facility.
Shear overload fracture (45° fracture surface) was also observed on the remaining Al wires of the conductor tested under higher bending amplitude (1.3 mm).
The results indicated that the rupture of the planar fracture surfaces observed in the external Al strands of the conductor tested under lower bending amplitude (0.9 mm) occurred by fatigue cracking (1 mm deep), followed by shear overload.
The coil performance is analyzed in light of the NbTi strand superconducting properties coming from the strand characterization program and of the full-size conductor tests carried out by CEA in the SULTAN facility.
The V-type fracture surfaces observed in some Al strands of the conductor tested under higher bending amplitude (1.3 mm) were also produced by fatigue cracking (approximately 400 μm deep), followed by shear overload.
In this paper, we use a new numerical model, called the Florida electro-mechanical cable model (FEMCAM) benchmarked against 40 different conductor tests, to study the influence of bending strain and current non-uniformity on the critical current and n-value of Nb3Sn strands and CICC cables.
YBCO coated conductors test in the experiment are from American superconductor (AMSC) and Shanghai Jiao Tong University (SJTU).
LABONE INC., Lenexa, Kan., a conductor of tests for insurance companies and drug screening for employers, said it would acquire an insurance-testing laboratory in Elmsford, N.Y., from MetLife Inc., New York, and provide laboratory services to MetLife.
A large cable-in-conduit-conductor (CICC) test facility has been designed and fabricated at the High Magnetic Field Laboratory of the Chinese Academy of Sciences CHMFLL) in order to meet the test requirement of the conductors which are applied to the future fusion reactor.
