The conference on Computer Simulation of Radiation Effects in Solids (COSIRES) is a regularly occurring international scientific conference for presenting and discussing recent achievements in the advanced computer modelling of surface and bulk phenomena stimulated by all forms of energetic particle (ion, neutron, electron, ...) irradiation. It is held biannually in different parts of the world, and has always attracted 100-120 attendees. == Scientific background == Radiation is omnipresent in nature, and utilized in numerous technological devices developed by man. Cosmic rays penetrate the entire biosphere, and affect us e.g. in the form of breaking of chemical bonds in our body (a possible source for cancer) and by causing electric signals known as upset events in semiconductor components. Also, natural fission events occurring in minerals provide an important way for chronological dating of geologic samples via fission track dating. Radiation occurs also in a wide variety of technological devices. Radiation damage is a serious problem in nuclear power plants, a problem that is estimated to be also significant in possible future fusion power plants. On the other hand, ion implantation is a key part of semiconductor device fabrication, and electron beams are routinely used for cancer treatment. In many cases the radiation effects are in fact beneficial, such as for defect engineering of semiconductors and sputtering-based secondary ion mass spectrometry analysis of materials. In electron microscopes, beam damage is one of the key issues limiting the reliability of the results. Fundamental scientific understanding of radiation effects is often not accessible by experiments, since they occur on very small time and length scales. Due to the complex nature of radiation effects, the theoretical work in the field has for a long time relied on computer simulations. Vigorous development of both computer hardware and theoretical methodologies which has occurred in recent years has pushed the field into the forefront of a modern science. Both for the detrimental and beneficial effects, it is very important to have good scientific understanding of the radiation effects, and obtaining such understanding is the primary aim of the COSIRES conference. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「International conference on Computer Simulation of Radiation Effects in Solids」の詳細全文を読む スポンサード リンク
