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.
