К010Х soft X-ray streak and single frame camera

    

Application:

The camera is intended for registration of images of fast running processes in soft X-ray spectral range and measurements of their spatially-temporal parameters in streak and single-frame modes of recorded imageRecord of the image from the image converter tube (ICT) screen is made by means of CCD readout unit with image input in the personal computer. Software provides the user with wide possibilities of processing the recorded image.

Article [53] in "Publications" section is devoted to designing and tests of this camera. The subjects of X-ray streak-cameras are reflected in articles [4, 19, 24, 29, 58].

Possible fields of application: 
  • Laser physics,
  • Nuclear physics,
  • Plasma physics including thermonuclear synthesis,
  • X-ray spectroscopy,
  • electrical breakdowns and discharges, etc.
The main components of the camera: 
  • PV-204XM an open (being evacuated during operation) time-analyzing ICT  with replaceable CsJ and Au photocathodes, one microchannel plate (MCP), one pair of  deflecting plates and a phosphor screen applied on a fiber-optic disk;
  • power supply unit;
  • two replaceable control units for microsecond and nanosecond sweeps and  frame durations of the same values;
  • RU-05M CCD readout system (1392x1032 pixels, 12-digit ADC, linear dynamic range ≥ 300) with an electrical (≤ 5 m) orfiber-optic (≤ 500 m) communicational line with the computer;
  • notebook with installed software;
  • "air" frame and slit test-objects etched in copper foil, which may be set closely to the photocathode for spatial resolution control;
  • holding plate for mechanical fixation of the camera on a work site.
