摘要: In an X-ray image intensifier tube entrance section is optimized in respect of quality, optical aberrations and efficiency. To achieve this, notably order to avoid photocathode charging phenomena, a separating layer having adapted electrical transverse conduction provided. reduce scattered radiation, edge portion the screen deactivated for relevant examinations. increase efficiency, use made double phosphor different absorption properties. compensate vignetting radial variation thickness or radiation properties luminescent itself used.
