    • A high voltage power cable termination with a current lead, a power cable having a first tube and an outer conductor, e.g., a superconductor, whose electrically conducting properties improve at low temperatures, arranged around the first tube and intended in use to be cooled to low temperatures by cryogenic fluid flowing through the first tube, a joint for electrically connecting one end of the current lead to the conductor at one end of the cable at or adjacent to one of the first tube, and a second tube communicating with the first tube at or adjacent to the joint for conveying cryogenic fluid to or from the first tube. The first and the second tube are arranged so that, in use, no cryogenic fluid conveyed by the tubes contacts the conductor or the current lead at the joint. The invention also relates to electrical apparatus, e.g., a high voltage induction device, having such a termination.

    • In order to provide a method and device for determination of the albedo or light absorption of a particle of random form, it is proposed that a particle is electrostatically charged and is positioned contact-free in an Ulbricht sphere by means of an electric field; that the particle thus positioned is illuminated with a measuring light beam passing through the Ulbricht sphere with defined intensity, defined beam cross-section and defined intensity distribution over this; that the intensity of the solely particle-based diffuse radiation in the Ulbricht sphere is measured by means of a sensor; that the cross-sectional area of the particle illuminated by the measuring light beam is determined; that the intensity of the solely reference particle-based diffuse radiation is measured in the same manner with a reference particle with known albedo; and that the albedo of the particle is determined from the ratio of the intensities of the particle-based and reference particle-based diffuse radiation taking into account the cross-sectional area of the particle illuminated by the measuring light beam and the cross-sectional area of the reference particle.
    • 为了提供用于确定随机形式的颗粒的反照率或光吸收的方法和装置,提出了一种颗粒被静电充电并且通过电场在Ulbricht球体中定位为无接触; 如此定位的粒子被照射通过Ulbricht球的测量光束,其具有确定的强度,限定的束横截面和在其上限定的强度分布; 通过传感器测量Ulbricht球体中仅基于粒子的漫射辐射的强度; 确定由测量光束照射的颗粒的横截面面积; 以与已知反照率的参考颗粒相同的方式测量单独参考的基于粒子的漫射辐射的强度; 并且考虑到由测量光束照射的颗粒的横截面面积和横截面积,基于粒子和基于参考颗粒的漫射辐射的强度的比率确定颗粒的反照率 的参考颗粒。
