In nuclear quadrupolar resonance (NQR) measurements on the heavy-fermion superconductor PuCoIn, in the temperature range 0.29 K 
75 K. The NQR parameters for the two crystallographically inequivalent In sites are determined, and their temperature dependence is investigated. A linear shift of the quadrupolar frequency with lowering temperature below the critical value 
is revealed, in agreement with the prediction for composite pairing. The nuclear spin-lattice relaxation rate 
clearly signals a superconducting (SC) phase transition at 
2.3 K, with strong spin fluctuations, mostly in-plane, dominating the relaxation process in the normal state near to . Analysis of the 
data in the SC state suggests that PuCoIn is a strong-coupling 
-wave superconductor.

Times Cited Count：5 Percentile：23.98(Physics, Condensed Matter)The results of In nuclear quadrupole resonance (NQR) measurements on PuIn are reported. Three of the four NQR lines of In expected for nuclear spin 
=9/2 are observed. The equal spacing of these lines at 20 K yields the NQR frequency of 
=10.45 MHz, and the asymmetry parameter of the electric field gradient, 
=0. The NQR line profile and the nuclear spin-lattice relaxation rate 
display an abrupt change at 14 K, which is associated with the onset of long-range antiferromagnetic order. The temperature dependences of the staggered magnetization 
, extracted from the NQR spectra, and below 
=14 K are well explained by the self-consistent renormalization (SCR) theory for spin fluctuations. In addition, scaling between 
and 
is also consistent with the predictions of SCR theory, providing further evidence that PuIn is a weak itinerant antiferromagnet in which spin fluctuations around the antiferromagnetic wave vector play a major role in the system's behavior at finite temperatures.

The ITER organization and 6 Domestic Agencies (DA) have been implementing the construction of ITER superconducting magnet systems. Four DAs have already started full scale construction of Toroidal Field (TF) coil conductors. The qualification of the radial plate manufacture has been completed, and JA and EU are ready for full scale construction. JA has qualified full manufacturing processes of the winding pack with a 1/3 prototype and made 2 full scale mock-ups of the basic segments of TF coil structure to optimize and industrialize the manufacturing process. Preparation and qualification of the full scale construction of the TF coil winding is underway by EU. Procurement of the manufacturing equipment is near completion and qualification of manufacturing processes has already started. The constructions of other components of the ITER magnet systems are also going well towards the main goal of the first plasma in 2020.

Times Cited Count：8 Percentile：49.7(Physics, Nuclear)Measurements of electrons from the decay of open-heavy-flavor mesons have shown that the yields are suppressed in Au+Au collisions compared to expectations from binary-scaled collisions. Here we extend these studies to two particle correlations where one particle is an electron from the decay of a heavy flavor meson and the other is a charged hadron from either the decay of the heavy meson or from jet fragmentation. These measurements provide more detailed information about the interaction between heavy quarks and the quark-gluon matter. We find the away-side-jet shape and yield to be modified in Au+Au collisions compared to collisions.

Times Cited Count：13 Percentile：61.59(Physics, Multidisciplinary)We report results of Co nuclear magnetic resonance measurements on a single crystal of superconducting PuCoGa in its normal state. The nuclear spin-lattice relaxation rates and the Knight shifts as a function of temperature reveal an anisotropy of spin fluctuations with finite wave vector 
. By comparison with the isostructural members, we conclude that antiferromagnetic 
-type anisotropy of spin fluctuations plays an important role in mediating superconductivity in these heavy fermion materials.

The main test program are the DC characterization of the conductor, the measurement of AC losses in conductor, the hydraulic characterization, the stability and the quench propagation, and the effects of cycling electromagnetic load. Based on and in support of this test program, an extensive campaign of predictive analysis has been initiated on a subset of the above-mentioned test program items and the results of the comparison of selected predictions from different laboratories will be presented and discussed. A sudden quench at 5.7-6.2 K and 45 kA is predicted. The computed temperature increase at the winding outlet is about 0.5 K for the pulse. These results will be compared with the experiment and used for an accurate prediction of the PF coil performance.
