Double-tuned light-absorption characteristics in the attenuated-total-reflection structure containing a metal-clad dielectric-film waveguide with a low-refractive-index buffer layer.

Optics letters

PMID: 19701443
Opt Lett. 1981 Aug 01;6(8):392-4. doi: 10.1364/ol.6.000392.

We have demonstrated that double-tuned absorptions have the characteristics of forming a flat peak in an attenuated-total-reflection structure containing a metal-clad dielectric-film waveguide with a low-refractive-index buffer layer. The double-tuned characteristics occur because the guided mode in the film...

PMID: 19044496
Rev Sci Instrum. 2008 Oct;79(10):10E512. doi: 10.1063/1.2974810.

An orbit following calculation code with full gyromotion under the ITER magnetic field configuration has been developed to investigate escaping alpha particle orbits in ITER and to determine the geometrical arrangement for alpha particle detection. The code contained the...

Ultralow-loss mirror of the parts-in-10(6) level at 1064 nm.

Optics letters

Uehara N, Ueda A, Ueda K, Sekiguchi H, Mitake T, Nakamura K, Kitajima N, Kataoka I.
PMID: 19859245
Opt Lett. 1995 Mar 15;20(6):530-2. doi: 10.1364/ol.20.000530.

We describe an ultralow-loss and high-reflectance mirror at 1064 nm. A Fabry-Perot cavity is fabricated with two mirrors to measure the finesse and the transmission efficiency on resonance. The finesse was cross checked by two different methods: measurements of...

A beam transport system for an intense He(-) beam source.

The Review of scientific instruments

Tanaka N, Kikuchi M, Nagamura T, Sugawara H, Takeuchi S, Kobuchi T, Okamoto A, Shinto K, Kitajima S, Sasao M, Wada M.
PMID: 18315133
Rev Sci Instrum. 2008 Feb;79(2):02A512. doi: 10.1063/1.2816967.

We have been developing a test stand for fast He(0) beam production. One of the major issues is how to transport effectively the He(+) and He(-) beams from which the He(0) beam is produced. The beam should be focused...

Diagnostics of a He(+) beam extracted from a compact magnetic bucket-type ion source.

The Review of scientific instruments

Sugawara H, Shinto K, Tanaka N, Takeuchi S, Kikuchi M, Okamoto A, Kitajima S, Sasao M, Wada M.
PMID: 18315199
Rev Sci Instrum. 2008 Feb;79(2):02B708. doi: 10.1063/1.2802282.

Performance of a compact He(+) ion source was investigated before installing it to the experiment system developed for studying the efficiency of autodetachment neutralization from He(-) to He(0). Dependence of the extracted ion current upon the plasma parameters and...

Relativistic quasidegenerate perturbation theory with four-component general multiconfiguration reference functions.

The Journal of chemical physics

Miyajima M, Watanabe Y, Nakano H.
PMID: 16460143
J Chem Phys. 2006 Jan 28;124(4):044101. doi: 10.1063/1.2161182.

Relativistic quasidegenerate perturbation theory (QDPT) using general multiconfiguration (GMC) reference functions is developed and implemented. It is the relativistic counterpart of the nonrelativistic QDPT with GMC reference and thus retains all the advantages of the nonrelativistic GMC reference QDPT,...

Endothelial nitric oxide synthase (NOS3) is one of the enzymes influencing nitric oxide (NO) function in the human brain. NO is a gaseous neurotransmitter that is involved in a variety of mechanisms in the central nervous system, such as...

Recent issues in contrast-induced nephropathy.
