[en] The beam profile monitor system based on infrared thermography provides a direct visual representation of the relative particle density distribution over the total cross section of a particle beam. Advantages of this monitor system, such as monitoring of the total beam cross section, fast scanning (video frequency), no vacuum feedthrough and applicable to high beam power result in an easy beam handling.

[en] A method of beam diagnosis, based on the application of infrared-thermography, is presented. The optical and electronical elements of a beam profile monitor are considered. In addition first experimental results are given. (author)

[en] This invention relates to a device for the measurement of relative density distribution and for the presentation of cross section geometry of accelerated proton, deuteron or other light particle beams during their application. A target is used for the measurement which can remain in the particle beam during irradiation and which absorbs only a small part of kinetic energy. The target has a thickness of at least 10 μm and is fixed within the beam tube system. It consists of a metal or carbon foil. A gas target is applicable, too

[en] The invention is aimed at determining the lateral distribution of radiation with high accuracy and less expenses. Its special fields of application are atomic, molecular, and ion beam profile determination, homogeneity controls in ion implantation, and light intensity distribution in laser beams. The aim could be achieved by refraining from external signal pre-amplification and changing the design of the detecting elements

[en] This invention relates to a circuitry for a controlled deflection of electron or ion beams usually applied to accelerators. It is the aim of the invention to ensure an effective irradiation without local thermal overloads at the irradiated material and to avoid interferences. The developed circuitry has such an effect that no radiation inversion points on the target occur

[en] A method of beam diagnosis based on the application of infrared thermography is presented. The main elements of a beam profile monitor are considered. In addition, the first results of experiments made at the Rossendorf Cyclotron are published. (orig.)

[en] After a brief review of the physical and hardware fundamentals of televison-aided thermographic investigations, two practical examples of nuclear and solid state research work are presented. The problems discussed concern studies of the relative density distribution in beams of particles (ions, electrons, neutral atoms) or of visible radiation on the one hand, and the optimization of operating conditions in heavy-current implantations (ion implantation in Si at ion beam currents up to 60 μA) on the other hand

[en] In the work the construction of a test stand for testing and optimization of ion sources of the Rossendorf cyclotron U-120 is represented. The design procedure and the construction of the electromagnet, the vacuum chamber with monant, the vacuum system, the power supply and the detecting system are demonstrated. The results of calculations of the motion of ions in the magnetic field are presented. (author)
