Deposition of impurity metals during campaigns with the JET ITER-like Wall

Nuclear Materials and Energy (2019)

A. Widdowson J.P. Coad E. Alves A. Baron-Wiecheć N. Catarino

Post mortem analysis shows that mid and high atomic number metallic impurities are present in deposits on JET plasma facing components with the highest amount of Ni and W, and therefore the largest sink, being found at the top of the inner divertor. Sources are defined as "continuous" or "specific", in that "continuous" sources arise from ongoing erosion from plasma facing surfaces and "specific" are linked with specific events which decrease over time until they no longer act as a source. This contribution evaluates the sinks and estimates sources, and the balance gives an indication of the dominating processes. Charge exchange neutral erosion is found to be the main source of nickel, whereas erosion of divertor plasma facing components is the main source of tungsten. Specific sources are shown to have little influence over the global mid- and high-Z impurity concentrations in deposits.

Addition of an insulating element to the Modified Markov Method for CdTe single crystals growth

Crystal Research and Technology (2004)

Edgardo Saucedo Carmen M. Ruiz L. Fornaro V. Corregidor E. Diéguez

Abstract CdTe single crystal, were grown by the Modified Markov Method. We have introduced an insulating element between the furnace and the growth chamber, trying to minimize the radiation effects in the crystal. Numerical simulation of the heat transfer phenomena predict a reduction of the axial temperature gradient in the growth chamber, confirming by numerical experimental measurements, leading to a more uniform growth. An improvement in the surface morphology and in the crystal quality as well was achieved, evaluated by the combination of X‐ray rocking curves, etch pit density determination and low temperature photoluminescence.

Study of Iron Gall Inks, Ingredients and Paper Composition Using Non-Destructive Techniques

Heritage (2019)

V. Corregidor Rita Viegas L.M. Ferreira L.C. Alves

Old manuscripts are among the most important elements of the cultural and historical heritage of ancient knowledge. Unfortunately, many of them suffer from degradation, mostly those written with iron gall inks. In the present work, a study using non-destructive techniques was designed with the aim of analyzing the elemental composition and structural characteristics of iron gall inks, reproduced in laboratory, paper and their interaction when the ink is deposited on paper, inducing the paper degradation. Proton induced X-ray emission, X-ray diffraction and Fourier-transform infrared spectroscopy provided the elemental and structural information, and photography under infrared (IR) and ultraviolet (UV) light allowed the differentiation between manufactured inks. Results show that the first step of inked paper deterioration is due to acid-hydrolysis of the cellulose and the presence of reactive Fe(II) species by reducing the crystallinity index of the paper, which is affected depending on the ink recipe and the starting raw materials. These results will be useful to future studies on ancient documents written with iron gall inks, which suffer deterioration due to ink corrosion, and to differentiate between the different paper degradation mechanisms.
