Equipment for Detection of Fast Processes
The Institute develops and fabricates the equipment for detecting and
measuring of the fast processes for the nuclear physical research and
the laser emission diagnostics:
• Gamma and neutron detectors of the high sensitivity (up to 2·10-9
A·cm2·s/quantum), the high time resolution (0.5 to 10 ns), and the high
linear current (2 to 10 A);
• Chronographic electronic-optical detectors of the optical radiation in
the wavelength range 300 to 1053 nm and subpicosecond time
resolution;
Equipment for Detection of Fast Processes
The Institute develops and fabricates the equipment for detecting and
measuring of the fast processes for the nuclear physical research and
the laser emission diagnostics:
• X-ray electronic-optical detectors for X-ray plasma image in the laser
nuclear fusion installations:
- Chronographic electronic-optical detectors with the picosecond time
resolution (3 ps) and the spectral detection range 0.1 to 10 keV;
- Multi-image electronic-optical detectors with the image duration 100 ps
and the number of images equal to 10.

Equipment for Detection of Fast Processes
The unique electro-vacuum devices are
developed to be used in the scintillation
detectors and the fast electronic-optical
detectors: the photoelectron multipliers and
the photo-elements of the high time
resolution, the X-ray and chronographic
electronic-optical converters. These
devices have the linear characteristic
current curve up to 10 A, the large gain
factor up to 106, and the high time
resolution (0.5 ns), so that they can be
applied for detecting the
subnanosecond processes.
