Superconductivity - Part 17: Electronic characteristic measurements - Local critical current density and its distribution in large-area superconducting films

IEC 61788-17:2013 describes the measurements of the local critical current density (Jc) and its distribution in large-area high-temperature superconducting (HTS) films by an inductive method using third-harmonic voltages. The most important consideration for precise measurements is to determine Jc at liquid nitrogen temperatures by an electric-field criterion and obtain current-voltage characteristics from its frequency dependence. Although it is possible to measure Jc in applied DC magnetic fields, the scope of this standard is limited to the measurement without DC magnetic fields. This technique intrinsically measures the critical sheet current that is the product of Jc and the film thickness d. The range and measurement resolution for Jcd of HTS films are from 200 A/m to 32 kA/m, with a measurement resolution of 100 A/m.

Supraconductivité - Partie 17: Mesures de caractéristiques électroniques - Densité de courant critique local et sa distribution dans les films supraconducteurs de grande surface

La CEI 61788-17:2013 décrit les mesures de la densité de courant critique local (Jc) et sa distribution dans les films supraconducteurs à haute température (HTS) de grande surface par une méthode inductive utilisant les tensions de troisième harmonique. La considération la plus importante pour effectuer des mesures précises consiste à déterminer Jc aux températures de l'azote liquide au moyen d'un critère de champ électrique et obtenir des caractéristiques courant-tension d'après sa dépendance vis-à-vis de la fréquence. Bien qu'il soit possible de mesurer Jc dans des champs magnétiques en courant continu appliqués, le domaine d'application de la présente norme est limité à la mesure sans champ magnétique en courant continu. Cette technique mesure de façon intrinsèque le courant de feuille critique, qui est le produit de Jc par l'épaisseur d du film. La plage et la résolution de mesure pour Jcd des films HTS est de 200 A/m à 32 kA/m avec une résolution de mesure de 100 A/m.

Superprevodnost - 17. del: Meritve elektronskih karakteristik - Krajevno kritična tokovna gostota in njena porazdelitev po površinsko obširnih razsežnih superprevodnih plasteh

Ta del IEC 61788 opisuje meritve lokalne kritične tokovne gostote (Jc) in njene porazdelitve na obsežnih visokotemperaturnih superprevodnih (HTS) filmih z induktivno metodo s pomočjo tretje-harmonskih napetosti. Najpomembnejši del pri natančnosti meritev je določiti Jc pri temperaturah tekočega nitrogena s kriterijem električnega polja in pridobiti lastnosti trenutne napetosti iz frekvenčne odvisnosti. Čeprav je mogoče Jc izmeriti v uporabljenih enosmernih magnetnih poljih [20, 21]2, se ta standard nanaša le na meritve brez enosmernih magnetnih polj. Ta tehnika meri kritični tok plasti, ki je rezultat Jc in debeline filma d. Obseg in ločljivost meritve za Jcd filmov HTS sta naslednja:
– Jcd: od 200 A/m do 32 kA/m (glede na rezultate, ne omejitve);
– Ločljivost meritve: 100 A/m (na podlagi rezultatov, ne omejitve).
