Abstract: The present invention relates to an apparatus for detection of radiation comprising a photocathode layer adapted to release photoelectrons in dependence on incident radiation; a radiation entrance arranged such that a beam of radiation can be entered into the apparatus through said radiation entrance and can impinge on said photocathode layer at grazing incidence; an electron avalanche amplifier adapted to avalanche amplify photoelectrons released from said photocathode layer; and a readout arrangement adapted to detect avalanche amplified electrons from said amplifier. The invention further relates to a corresponding method for detection of ionizing radiation and to an arrangement for use in planar beam radiography comprising the detector apparatus.

Abstract: To reduce the size of a photomultiplier tube (1), a side tube (2) is fixedly secured by welding to a stem plate (4) while an inner surface (2c) of the lower portion (2a) of the side tube (2) is maintained to be in contact with an outer edge (4b) of the stem plate (4). As a result, there is no projection like a flange at the lower portion of the photomultiplier tube (1). Therefore, though it is difficult to perform resistance welding, the outside dimensions of the photomultiplier tube (1) can be decreased, and the side tubes (9) can densely abut to one another even if the photomultiplier tubes (2) are arranged when applied. Hence, high-density arrangement of photomultiplier tubes (1) are realized by assembling metallic stem plate (4) and the side tube (2) by, for example, laser welding.

Abstract translation: 为了减小光电倍增管（1）的尺寸，侧管（2）通过焊接牢固地固定在杆板（4）上，而侧管（2）的下部（2a）的内表面（2c） ）保持与杆板（4）的外边缘（4b）接触。 结果，在光电倍增管（1）的下部没有像凸缘那样的凸起。 因此，虽然难以进行电阻焊接，但是即使在施加光电倍增管（2）时，也可以减小光电倍增管（1）的外部尺寸，并且侧管（9）可以彼此紧密地邻接 。 因此，光电倍增管（1）的高密度配置通过例如激光焊接组装金属杆板（4）和侧管（2）来实现。
