Description

Field of technology

The utility model relates to an integrated X-ray cooler using a flat anode to stop an electron stream emitted by the cathode, thereby generating an X-ray beam.

BACKGROUND OF THE INVENTION

Flat anode X-ray emitters for generating an X-ray beam are known. In these emitters, the electron flux emitted by the cathode is stopped at the anode, acting as a target, whereby an X-ray beam is generated. In them, most of the energy of the electron flow is converted into heat energy and only a small part is emitted in the form of X-rays. Heating the anode limits the energy that can be released in the X-ray beam and narrows the application of this type of emitters to generate single pulses, followed by pauses needed to cool the anode. In these radiators the cooling is performed by:

- heat radiation;

- heat transfer from the periphery of the anode to its supporting structure;

- convection or forced movement of the gaseous medium in which the emitter operates (usually air). When the emitter operates in a vacuum environment (eg space), this is not applicable.

Technical essence of the utility model

The task of the utility model is to create a cooler, allowing to remove the heat energy released from the anode in a pulse-continuous mode of generating an X-ray beam. The cooler must allow the energy of the X-ray beam not to be limited by the time required to cool the target between two pulses, but to be influenced only by the parameters of the electron flux used.

This problem is solved with a cooler consisting of a base, on which the flat anode of the radiator is attached by the first seal, and on the periphery of the base there are distribution and collector channels in the form of semicircles, equipped with inlet and outlet nozzles for the heat carrier, as at the bottom of the channels at certain distances there are openings passing through the base, in the lower part of which 5 by a second seal a casing is attached.

The advantages of the cooler using a layer of heat carrier that flows around the flat anode, according to the utility model are the following:

- allows to create a source of 10 X-ray beams using a flat anode irradiated with a stream of electrons, which source to work in pulse-continuous mode and provide a certain dose for a certain time, without the need to provide additional pauses 15 for cooling at the anode;

- the cooler can be sized and used simultaneously to filter the spectrum of the emitted X-ray flux, thus eliminating the need for an additional 2 0 component in the X-ray system.

Exemplary implementation of the utility model 40

In FIG. 1 shows an X-ray radiator cooler with a housing 10 and a flat anode 11 acting as a target for stopping an electron flux emitted by the cathode, whereby an X-ray beam is generated. The cooler consists of a base I, which is attached by a first seal 4 to the housing 10 and the anode 11 of the radiator. Along the peripheral semicircles of the base 1 are located closed at both ends channels 5 θ distribution 2 and collector 3, which respectively

2108 Ul are connected to an inlet nozzle 5 and an outlet nozzle 6. At the bottom of the channels at certain distances there are openings 12 and 13, respectively of the distribution and collector channel, which openings pass through the base1. 5

The housing 7 is attached to the base 1 and sealed around its entire periphery by a second seal 8. The coolant 9 enters through the inlet nozzle 5 into the distribution channel 2, where it passes through the holes 12 in its bottom 10 in the space between the anode 11 of the radiator and the housing 7 cooler. By flowing around the surface of the anode 11, the coolant cools it and reaches the holes 13 in the bottom of the collector channel 3, through which it enters and exits through the outlet 15 of the nozzle 6. Thus achieves the necessary cooling of the anode 11, which can be regulated and the flow rate of the passing heat carrier 9. The use of a sufficiently thin layer of heat carrier and a suitable material for 20 casings allows the cooler to have practically no effect on the X-ray parameters.

With a suitable choice of the casing material and its thickness, as well as the heat carrier and the thickness of its layer, the cooler can also be used as an integrated filter of the X-ray emission spectrum.
