    The streak tube is intended for soft X-ray fast running processes image registration in a streak modes. It has replaceable semitransparent Au or CsJ pohotocathodes applied on a 100 nm parylene film or 10-15 μm beryllium foil,an  accelerating gird electrode closed to the photocathode, a focusing electrode, one pair of deflecting plates with pin inputs, one MCP and a blue/green screen applied on a fiber-optic disk.
   The streak tube is supplied with a flange. Using this flange the tube is vacuum-tight coupled with a flange of pumped camera where the registered process is developed The flange is connected to a streak tube shell using a siphon  what make it possible to rotate streak tube optical axis in any directions up to 100 angle related to a direction of registered radiation incidence at the photocathode. It is necessary to avoid ingress of rather hard X-ray radiation which can be occur simultaneously with soft X-ray radiation at MCP and to avoid appearance of spurious background on the sweep image of detected process
