The cold cathode X-ray tube (PSF) uses an integrated photomultiplier tube as a source of electrons instead of traditional cathodes. X-ray radiation is controlled by the magnitude of the luminous flux incident on the photocathode of the PMT. An LED, a laser, a lamp or any other source can be used as a light source.

The target of the vidicon LI501-1MK 2/3 “is made on the basis of cadmium selenide. Magnetic focusing and electrostatic deflection are used.
