    Abstract: A method and a device for operating and focusing a tomographic x-ray unit using an electron beam and embodying at least one electron gun (1), an anode (2) at which the gun is aimed as well as the x-ray detectors (5) needed to produce a tomographic photograph. In order to construct a device with a sufficiently short exposure time and capable of taking tomographic photographs of fast-moving objects, it is particularly characteristic of this invention that an electron beam (8) emitted by an electron gun (1) is roughly deflected at a hole (4) in the focusing plane (3) which, by means of focusing field lines, draws the electrons into the hole, focuses and accelerates the electron beam which strikes the surface of the anode (2), generating an x-ray source, and that the focusing hole (4) is moved in regard to the anode (2) to generate a series of x-ray sources needed to produce a "layerwise" tomographic photograph of the object under examination.

    Abstract: The present invention concerns the measuring of a silicon coating on paper or cardboard moving in the form of a continuous web and which may as fillers contain substances containing silicon such as kaolin, or aluminum silicate. By x-ray radiation from a primary radiation source (3) and passing through the web is excited the characteristic x-ray radiation of an element, in a secondary radiation source (7) on the silicon coating side of the paper web (1), having a higher ordinal number than silicon (Si). The exciting radiation is sent obliquely against the surface of the paper or cardboard, whereby the irradiation of the surface is accentuated and the characteristic x-ray radiation of the silicon in the silicon coating can be excited. The exciting radiation also partly excites the silicon in the filler, but in this case it will be accompanied by the characteristic x-ray radiation of the metal associated with the silicate, such as aluminum in the instance of kaolin. These two fluorescence radiations are measured using a semiconductor detector (9) with good energy discriminating capacity, the quantity of silicon coating being calculable from the silicon energy peak recorded in the spectrum from this detector when it is corrected, as in the exemplary case, to eliminate with the aid of the aluminum peak the contribution of the filler and when in the scattered energy peak measured from the spectrum the irradiation correction is taken into account. If there is coating on both sides, two measuring heads are placed one after the other in the web's direction of travel by which the surface fluorescence is recorded from different sides.

    Abstract: The invention concerns a procedure and a means for creating an electron curtain (5) intended to be used in irradiating a surface (8) and adjustable as to its intensity distribution. The electron curtain is elicited by producing with an elongated filament (2) placed in a chamber (1), free electrons in a space (6) surrounding the filament, by accelerating the electrons by means of an electrode structure (3) confining the space and by directing the electron curtain formed by the accelerated electrons out from the chamber through a window (4) permeable to electrons in its wall. It is a substantial novelty in the invention that regulation of the intensity distribution of the electron curtain (5) takes place by use of an elongated body (9) of magnetically soft material and of a row of magnets constituted by magnets (10) placed side by side, one of the two being disposed substantially parallelling the filament (2) behind the filament as seen from the direction of the window (4) of the chamber (1) and the other being disposed outside the window of the chamber before the electron curtain, the basis for the regulation achievable with the magnets being the absorption, dependent on the strength of the magnetic field, of electrons in the electrode structure (3). The magnets (10) being functionally independent of each other, the intensity of the electron curtain can be adjusted to be uniform or to vary as desired at different points of the curtain.

    Abstract: The objective of the invention is a method for detection of alien matter contents in gas, in which method the gas and the substances contained in it are ionized in an ionization room (1). By the present methods impurities in gases cannot be determined fast and in small concentrations. In the method of the invention the ions contained in the gas are separated in a separation section (2) into positive and negative ions, of which at least the ions of either sign are led into a narrow analyzer channel (4). There, due to the capillary force, they are forced to move in the middle section of the channel, from where they are deflected by electric fields of different strength caused by different voltages (U1-U10) into an electrode located at the edge of the channel, where they cause ion current (I1-I10). On the basis of ion currents a current spectrum is made, on the basis of which different substances are detected and their concentrations determined with the aid of corresponding spectra obtained with standard samples of different substances.

    Abstract: The application of the electron beam technique in the polymerization of surfaces and purification of flue gases, for instance, often has a high demand of energy. The performance of prior art emitters, often considerably less than 50%, is thereby a major drawback. In the present method, low-energy shaping acceleration is applied first and thereafter the electrons are passed through windows very ideally and homogeneously by the proper acceleration. By means of the method, several successive and/or parallel windows can be provided in the device, the electron power being distributed evenly between said windows.

    Abstract: A method for detection of alien matter content in gas, in which the gas and the materials contained in it are ionized in an ionization room (1). The present methods are inaccurate and unreliable. The invention is based on a method, in which the ionized gas is led through chambers (2) containing different electric fields, out of which at least from one of the chambers the field current is measured, from which a signal is obtained, which describes the existence of alien matters in the gas. More parameters are obtained for detection of different materials by measuring favorably the currents passed through several electric field chambers as well as possibly by branching off from the ionization source the flow to different analysis lines of the electric field chambers.
