Laiku je težko pokazati s prstom na napredek na področju raziskav fuzije, posebej zato, ker po 50 letih v omrežje še vedno niso dale niti miliwatta elektrike. Pa sta gornja naslova točna? Od začetka raziskav smo se morali soočiti z vrsto izzivov, npr. s tem, kako ograditi plazmo s temperaturo, ki je desetkrat višja od tiste v središču sonca, in kako jo izolirati od sten reaktorske posode, da se ne bodo stalile. Mnoga od vprašanj smo rešili, a številna ostajajo. Da bi te raziskave v Evropi postale prednostne, smo razvili t.i. Fuzijski načrt z mednarodnim fuzijskim reaktorjem ITER in International Fusion Materials Irradiation Facility (IFMIF) kot glavnima raziskovalnima centroma. Na kratko bomo pojasnili delovanje jedrske fuzije, nato pa se dotaknili več problemov, ki jih magnetna ograditev odpravlja. Predstavili bomo pregled preostalih odprtih vprašanj skupaj s strategijo, kako najti ustrezne rešitve. Osrednji del predavanja bo posvečen mednarodnemu ITER tokamaku. Ta naprava, ki jo gradimo v Cadarachu v južni Franciji, je eden največjih znanstvenih eksperimentov na svetu in bo oddajala desetkrat več moči, kot je bo trošila.<o:p></o:p></span></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt;text-align:justify'>Predavanje bo v angleščini.<o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;margin-bottom:12.0pt'><strong><span style='font-family:"Calibri","sans-serif";color:red'>Lepo vabljeni!</span></strong><strong><span style='font-weight:normal'><o:p></o:p></span></strong></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><span style='font-size:12.0pt;font-family:"Times New Roman","serif";mso-fareast-language:SL'><br clear=all style='page-break-before:always'></span><p class=MsoNormal><span style='color:black'>We invite you to the 10th Institute colloquium in the academic year 2014/15.

For the layman it is difficult put a finger behind the progress in the field of fusion research. This is especially because after more than 50 years of research still not even a milliwatt of electricity has been delivered to the grid. But are the abovementioned slogans correct? Since the start of fusion research many different challenges had to be overcome. For example: how can plasma be confined at temperatures that are 10 times higher than in the centre of the sun and how can we isolate this hot plasma from the walls of the reactor vessel such that they will not melt. Many of the original challenges have been overcome in the global fusion research. But still much research needs to be done to tackle the remaining challenges. To prioritize the research in Europe, a Fusion Roadmap has been developed with the international fusion reactor ITER and the International Fusion Materials Irradiation Facility (IFMIF) as main research facilities. We will first shortly explain the principle behind nuclear fusion. Subsequently, we will take the audience through several of the challenges which have been overcome in magnetic confinement fusion. We will present an overview of the challenges that are still remaining, along with a strategy to find adequate solutions. The focus of the talk will be on the international ITER tokamak. This device which is being erected in Cadarache in southern France is one of the world’s largest scientific experiments and is designed to get 10 times more fusion power as input power.<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Cordially invited!<o:p></o:p></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p></div></body></html>
