Times Cited Count：6 Percentile：31.16(Optics)A demonstration of coherent quantum control for ultrafast precise selection of closely-lying states is reported. A phase-locked pair of femtosecond laser pulses is generated through a pulse shaper to excite the ground-state cesium atom to the Cs(7) and Cs(7) states by two-photon absorption. The excited state population is measured by detecting fluorescence from each spin-orbit state. By controlling the phase-difference of the pulse pair, an ultrafast precise selection is accomplished. The contrast ratio of the maximal to minimal selection ratio exceeds 10
with the delay less than 400 fs.

JAEA is procuring conductors for ITER Central Solenoid (CS) and has evaluated its superconducting performance using CS Model Coil Test facility. We measured Tcs values during cyclic charge of 16,000 cycles and warm-up and cool-down cycle of 3 times. And we measured effect of coil deformation by electro-magnetic force on Tcs values and performed quench test. In this presentation, test method will be reported.

This paper reports the preliminary results of the magnetotelluric (MT) survey aiming to evaluate the three-dimensional distribution of fossil seawater in the Horonobe area. The MT survey was conducted in the area of 3 km square adjacent to the Horonobe Underground Research Laboratory at 60 points. Our results showed that the distribution of the resistivity varied in accordance with the geological structure. This survey was funded by the Ministry of Environment, Trade and Industry.
