Apparatuses and methods are provided for applying accelerated electrons to a gaseous medium by means of an electron beam generator, which has at least one cathode for emitting electrons and at least one electron exit window, wherein a) the at least one cathode is annular and the at least one electron exit window is in the form of an annular first hollow cylinder, the annular electron exit window in the form of the first hollow cylinder forms an inner wall of an annular housing of the electron beam generator, wherein the electrons emitted by the cathode are accelerated to the ring axis of the annular housing; b) an annular second hollow cylinder is arranged within the electron exit window in the form of the first hollow cylinder and delimits an annular space between the first hollow cylinder and the second hollow cylinder; c) a cooling gas is fed through the annular space between the first hollow cylinder and the second hollow cylinder; and d) the gaseous medium to which accelerated electrons are to be applied is fed through the second hollow cylinder.

Apparatus and method for applying accelerated electrons to gaseous media

The present invention relates to a method for irradiating a population of mammalian cells comprising at least one target mammalian cell with electron beams and/or X-rays, characterized in that: (i) a composition comprising a population of mammalian cells is irradiated in vitro with electron beams and/or X-rays, the population of mammalian cells containing at least one target mammalian cell and the dose rate being within the range from 5 Gy/sec to 10Gy/sec, and (ii) optionally viable target mammalian cells are isolated or enriched from the population of mammalian cells, and to agents obtainable thereby and to uses thereof.

Methods and Apparatus are provided for irradiating a liquid with accelerated electrons. The liquid is prepared. The liquid is mixed with particles having at least one luminescent substance, where the particles are formed such that the particles are dispersed in the liquid after mixing. The liquid is irradiated with an electromagnetic radiation, which induces the at least one luminescent substance to luminesce. An actual value of a physical quantity characterizing the luminescence of the luminescent substance is detected. The liquid is irradiated with accelerated electrons until the detected actual value corresponds to a target value.

Method for irradiating a liquid with accelerated electrons

An apparatus is provided for generating accelerated electrons, including a housing; an inlet for supplying a working gas; at least one first cathode; and at least one first anode, between which a corona discharge plasma can be generated. Ions from the corona discharge plasma can be accelerated onto the surface of a second cathode. Electrons emitted by the second cathode can be accelerated in the direction of the electron exit window by means of a second electric voltage applied between the second cathode and a second anode. The housing, the second cathode, and the electron exit window are ring-shaped. The ring-shaped space is divided into ring segments. Each ring segment has at least one wire-shaped electrode, which extends through the ring segment. At least one separate power supply device is associated with each ring segment, by means of which the strength of the electrical current is adjustable.

Apparatus for generating accelerated electrons

An apparatus includes at least one electron beam generator for generating accelerated electrons with which bulk material particles are impingeable during free fall. The electron beam generator has an annular design in which the electrons are emitted and accelerated by an annular cathode. The electrons exit from an electron outlet window in the direction of the ring axis. The annular electron beam generator is arranged in such a way that the ring axis of the electron beam generator is oriented perpendicular to, or at an angle of up to 45&#xb0; from the horizontal. The apparatus may further include a device for separating bulk material particles arranged above the annular electron beam generator, the bottom wall of said device having at least one opening out of which the bulk material particles fall and, from there, fall through the ring which is formed by the electron beam generator.
