Mössbauer spectrometer MsAa-3
No full textThe paper is aimed at the description of the newly developed Mössbauer spectrometer MsAa-3. The spectrometer MsAa-3 consists of a high quality gamma-ray spectrometer including either a proportional gas detector head or a scintillation detector head, a transducer driving system including the transducer, data storage system, and data communication system based on the TCP/IP protocol. Additionally, the Michelson-Morley interferometer is provided for precise calibration of the transducer velocity. The spectrometer is equipped with an integrated simple temperature controller. All the essential functions are remotely controlled over the TCP/IP link allowing for the spectrometer set-up as the stand-alone unit in the computer network, e.g. on the Internet. External gamma-ray detectors or external complete nuclear blocks could be used as well. The spectrometer is equipped with software allowing for setting all the functions, to perform on-line control, and retrieve data. The Mössbauer data processing software MOSGRAF is enclosed as well. The latter software allows for the calculation of the variety of velocity reference functions
Systematic Investigation of Self-Correlation Functions in Cubic Lattices; Mono- and Divacancy Mechanisms
No full textFeasibility study on the micro-foil internal conversion electron (MICE) detector application to high-temperature emission Mössbauer spectroscopy
No full textAbstract Detailed calculations have been performed to assess potential applicability of the MICE-CEMS detector (CEMS -conversion electron Mössbauer spectroscopy) to the high temperature emission Mössbauer spectroscopy by means of the keV 41 . 14 transition in Fe 57 . The comparison was made with the standard transmission method using either proportional or semiconductor detector. It was found that for typical source matrices used in the investigations performed at high temperatures the MICE-CEMS detector yields poorer results than the high quality semiconductor detector. Therefore the development of the dedicated MICE-CEMS detector is unjustified for this particular application
Mosgraf - 2009 : the Mössbauer data processing suite of applications
No full textThis contribution gives general description of the Mössbauer data processing suite of applications Mosgraf- 2009. The suite is designed to process data obtained in the energy domain. It contains many applications to generate off-line functionality files of the spectrometers and many applications to pre-process data or to plot results of the calculations. The suite is designed for the Microsoft Windows registery mark systems and it is compatible with the MsAa-x spectrometers of the RENON family. It could be installed on the same computer as the spectrometer drivers provided a broadband Ethernet link is available for the computer in question. Applications are provided to accept data from other spectrometers as well. The suite contains a large collection of the applications to simulate or fit experimental data
Roughness Method to Estimate Fractal Dimension
No full textA method based on the pattern roughness was introduced for determination of the fractal dimension and tested for fractals like the Sierpiński carpet, the Sierpiński triangle, standard Cantor set, the Menger sponge and the Sierpiński tetrahedron. It was tested for non-fractal pattern like two- and four-dimensional gray scale random dust as well. It was found that for all these patterns the Hausdorff dimension is reproduced with relatively high accuracy. Roughness method is based on simple, fast and easy to implement algorithm applicable in any topological dimension. It is particularly suited for patterns being composed of the hierarchy of structures having the same topological dimension as the space embedding them. It is applicable to "fuzzy" patterns with overlapping structures, where other methods are useless. It is designed for pixelized structures, the latter structures resulting as typical experimental data sets
