We report on studies of a diamond sample with strong gradient NV− concentration (between 4 and 36 ppm over 1.5 mm) created by inhomogeneous irradiation an electron beam. The was characterized spatially resolved luminescence ODMR spectra spatial distributions concentration, strain splitting, relaxation times T1, T2. Such may find applications in designing optimum conditions for numerous spectros...

XML itself does not support hypermedia, but the XLink standard has been defined to make XML usable for hypermedia. One of XLinks most interesting features is its support for external links and linkbases, which makes it possible to create links between resources without having to change the resources. In order to use these links, user agents must access linkbases and query them for relevant link...

Abstract This lecture introduces various kinds of spin rotating devices used in present particle accelerators. They include Siberian Snakes for polarization preservation and rotators creating a specific orientation experimental locations. Following the analysis rotation different types magnets, approaches designing are discussed. Considerations appropriate design choices dependence on beam ener...

Introduction: Monte Carlo calculation method is considered to be the most accurate method for dose calculation in radiotherapy. The purpose of this research is comparison between 6 MV Primus LINAC simulation output with commissioning data using EGSnrc and build a Monte Carlo geometry of 6 MV Primus LINAC as realistically as possible. The BEAMnrc and DOSXYZnrc (EGSnrc package) M...

Failure maps of sandwich panels such as beam, plate and shell are of great importance in designing such structures. In this paper, failure maps of sandwich beams with composite skin and honeycomb core are obtained. The effect of transverse shear in skins and core and the effect of double walls of honeycomb core have been taken into account. Shear deformation of skins and core are assumed to be ...

The loss propertiesof semiconductor laser beams propagating in hollow waveguides (HWGs) are crucial several applications. attenuation coefficient of the distributed feedback quantum cascade (DFB-QCL) HWG was quantitatively determined by measuring its beam profile and power along length HWG. experimental reliability evaluated, with measurement uncertainties as low 2.6% 0.5% for ful...

An inexpensive photoreactor using LED light sources and a fibre-optic CCD spectrophotometer as a detector was built by designing a special cell holder for standard 1.000 cm cuvettes. The use of this device was demonstrated by studying the aqueous photochemical reaction of 2,5-dichloro-1,4-benzoquinone. The developed method combines the highly quantitative data collection of CCD spectrophotomete...
