Ê010Õ 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 image.
Record
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].

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) or
fiber-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.
