Abstract: Linear ribs are formed radially with a center at a through-hole on one face of an X-ray transmissive film (radiolucent film) in an X-ray transmissive window (radiolucent window) to be used for an X-ray detector (radiation detector). The X-ray transmissive window faces a sample. A beam for irradiation to the sample passes through the through-hole, and X-rays (radiation) are radially emitted on a line extending through the through-hole and enter the X-ray transmissive window. Since the linear ribs are formed radially with the center at the through-hole, even X-rays entering at shallow angles with respect to the X-ray transmissive window are transmitted through the X-ray transmissive window at a probability equivalent to X-rays entering at deep angles. More X-rays are transmitted through the X-ray transmissive window, and thus the X-ray detector can detect X-rays with high efficiency.

Abstract: An x-ray tube can include an electron-emitter, which can include a tube-shape with a minimum inside diameter of at least 0.5 millimeters. The electron-emitter can provide field-emission of electrons, and thus can avoid the electrical power required for heating, and can avoid degradation due to high temperature of, a thermionic-emission electron-emitter. This type of electron-emitter, with a tube-shape, can have a relatively large electron-emission region, allowing high electrical current without excessive current density.

Abstract: The invention relates to a radiation application apparatus for applying radiation at a location within an object. The radiation application apparatus comprises a transforming unit (2) for being arranged within the object at the location and for transforming ultrasound energy to electrical energy, and a radiation source (4) for being arranged within the object and for generating radiation (5) to be applied at the location within the object, wherein the radiation source (4) is driven by the electrical energy. Since the transforming unit transforms the ultrasound energy to electrical energy being used by the radiation source, it is not necessary to transfer electrical energy to the radiation source, i.e., for example, corresponding cables, which may have to be isolated, are not necessarily required. Insulation problems and corresponding safety problems, which may be present, if cables, in particular, corresponding high voltage cables, are used, can therefore be reduced.
