Design and implementation of an electrons detector in Mössbauer spectroscopy for reflection
A proportional detector for gas flow was designed, which can be applied to analyze both, bulk and thin films samples, using the Conversion Electron Mössbauer Spectroscopy technique (CEMS). The prototype is a stainless steel cylindrical chamber with extrusions for the input and output gas flow, condu...

| description |
A proportional detector for gas flow was designed, which can be applied to analyze both, bulk and thin films samples, using the Conversion Electron Mössbauer Spectroscopy technique (CEMS). The prototype is a stainless steel cylindrical chamber with extrusions for the input and output gas flow, conductive strands and a sample holder which is bound to a micrometer, which allows to vary the distance between the sample and the copper strands. A gas mixture of 95% He + 5% CH4, which serves as signal multiplier gas and in turn controls the electron multiplication avoiding discharges that can damage the surface of the sample was used. The device was calibrated acquiring ICEMS spectrum for a sample containing iron, adjusting it with the MOSSFIT program, obtaining reported values from the hyperfine parameters. |

El prototipo es una cámara cilíndrica de acero inoxidable, con extrusiones para la entrada y salida de flujo de gas, filamentos conductores y un portamuestras que está unido a un tornillo micrómetrico el cual permite variar la distancia entre la muestra y los filamentos de cobre. Se usó una mezcla de gases, 95% He + 5% CH4, que cumple la función de gas multiplicador de la señal y a su vez controla la multiplicación de electrones los cuales pueden dañar la superficie de la muestra. El dispositivo fue calibrado adquiriendo el espectro ICEMS para una muestra con contenido de hierro, se realizó el ajuste de éste con el programa MOSFIT obteniendo valores reportados de los Parámetros Hiperfinos.Se construiu um detector proporcional de fluxo de gás para detectar elétrons da superfície de amostras em volume e películas finas utilizando a técnica de Espectroscopia Mössbauer de elétrons de conversão (CEMS).
