Creators

Description

The material of the superconducting screening lenses of the electron microscope is subject to X-rays. So that the superconducting property is not destroyed, sopper or silver is mixed with the niobium-tin sintered metal. The vacuum tubes consists of silver, German silber, a palladium-silver alloy or a platinum-iridium alloy (selection of range of wave lengths, critical wavelength). (RW)

Abstract (German)

Das Material der supraleitenden Abschirmlinsen des Elektronenmikroskops ist Roentgenstrahlung ausgesetzt. Damit die Supraleitfaehigkeit nicht zerstoert wird, ist dem Niob-Zinn-Sintermetall Cu oder Ag zugemischt. Die Vakuumrohre bestehen aus Ag, Neusilber, einer Palladium-Silber-Legierung oder einer Platin-Iridium-Legierung (Auswahl eines Wellenlaengenbereiches, kritische Wellenlaenge). (RW)
