چکیده

In this study we present details of a portable system which contains an X-ray source and heater, designed to irradiate and heat samples within a quartz glass tube for electron spin resonance (ESR) dating. The spatial distribution of the X-ray beam was measured with a radiation sensitive film and the images were scanned and mapped using the Risoescan software. The reproducibility of irradiations was checked by multiple irradiations to alanine. The results confirmed that X-ray irradiations give reproducible doses to samples. The heating component can heat samples between 100◦C and 600◦C and can be used for preheating after irradiation and for resetting the natural signal for regeneration.

MAGNETISATION AND ELECTRON SPIN RESONANCE STUDIES OF TETRAHEDRAL AMORPHOUS CARBON

The magnetisation and electron spin resonance (ESR) spectrum of two specimens of tetrahedral amorphous carbon (ta-C), deposited from a filtered cathodic arc, were measured over a wide temperature range. The magnetisation was found to consist of superparamagnetic, paramagnetic and diamagnetic contributions. The superparamagnetic contribution resembled that recently found in carbon prepared from ...

Electron Spin Resonance (ESR) Dating of Calcareous Fault Gouge of the Ushikubi Fault, Central Japan

The ages of fault events of active faults have been estimated using electron spin resonance (ESR) signals of siliceous gouges. This technique of ESR method is limited by obtaining only ages that are greater than tens of millennia. So this study focuses on developing a new technique of using calcareous gouges to gain an insight into the ages of latest seismogenic event within the Holocene. For t...

ESR investigation of sucrose radicals produced by 0.25−4.5 Gy doses of X-ray irradiation

We investigated stable radicals produced by 0.25-4.5 Gy doses of X-ray irradiation of sucrose. Electron spin resonance (ESR) is able to observe the signal from sucrose irradiated at 0.25 Gy. The ESR signal intensity of the radicals is related to the accumulated dose, and it increases linearly with increasing absorbed dose. In addition, we examined the effect of dose rate (0.50-1.5 Gy/min) on th...

Electron Spin Resonance (ESR) studies on radical scavenging activity of gamma ray irradiated pepper

The properties of radicals induced in the gamma ray irradiated pepper were investigated by means of spin trapping method and CW-ESR spectroscopy. Three radicals were found in the specimens irrespective of irradiation. The representative ESR spectrum of pepper is composed of a sextet centered at g = 2.0, a singlet at the same g-value, and a singlet at g = 4.0. The first signal is attributable to...

Electrically detected electron spin resonance in a high-mobility silicon quantum well.

The resistivity change due to electron spin resonance (ESR) absorption is investigated in a high-mobility two-dimensional electron system formed in a Si/SiGe heterostructure. Results for a specific Landau level configuration demonstrate that the primary cause of the ESR signal is a reduction of the spin polarization, not the effect of electron heating. The longitudinal spin relaxation time T1 i...
