Times Cited Count：80 Percentile：90.84(Physics, Multidisciplinary)We study polyamorphism of BO glass using X-ray diffraction up to 10 GPa in the 300-700 K temperature range, in situ volumetric measurements up to 9 GPa, and first-principles simulations. The glass undergoes two-stage transformations under pressure including a gradual increase of the first B-O (O-B) coordination numbers above 5 GPa. The fraction of boron atoms in the fourfold-coordinated state at P
10 GPa is smaller than was assumed from inelastic X-ray scattering spectroscopy data, but is considerably larger than was previously suggested by the classical molecular dynamics simulations. The observed transformations under both compression and decompression are broad in hydrostatic conditions.

Negatively charged nitrogen-vacancy (NV
) centers were created in high quality IIa diamonds by nitrogen (N) implantation. To identify implanted N atoms and their incident position, micro ion beams of 
N (natural abundance 0.37%) were applied. Since the reduction of 
C affects an increase in T, N implantation into a CVD diamond with high purity of 
C (99.99%) was carried out. As a result, the value of T for both NV and 
NV centers (NV centers are created from N atoms originally existing in the diamond and vacancy introduced by implantation after annealing) was obtained to be about 2 ms. By optically detected magnetic resonance (ODMR) measurements, the creation yield of both NV and NV was estimated.

We have measured optically-detected magnetic resonance (ODMR) of single spin of NV center in a high purity C enriched CVD diamond created by N ion implantation. Detailed ODMR measurements of individual NV centers revealed that both NV and NV were created by the N implantation with a ratio of [NV]/[NV] 
1 and a high conversion yield of 70-100% for [NV+NV]. The spin coherence time of 
was measured to be 2 ms at room temperature, which is the longest ever recorded in implanted samples. This result is expected to have a significant impact on realizing NV based applications.

Non-uniformity of the composition is an issue when evaluating fuel debris's criticality characteristics. Critical experiments using the modified STACY are planned to validate the criticality effects of the non-uniformity. In this presentation, the results of the critical experiment their experimental core arrangements have large non-uniformity effects, and their experimental analyses are shown.
