Ivan participated in the ICSLS 2024 conference

The ICSLS 2024 conference was held in Japan from 2nd to 7th June at Prefectural Budokan in Otsu. Ivan took part at this conference, where he had two posters. One poster was about the joint work with LHD colleagues on the application of generative artificial intelligence in modeling of emitted tungsten UTA structure in EUV spectral range. The second poster was the presentation of NOVA2LIBS4fusion project results regarding the study of separation of hydrogen and deuterium spectral lines relevant for tritium retention studies.

Finally, he also had the honor of visiting the NIFS facility in Toki. Here, he held a seminar about the results disseminated at the conference, and also took a tour of LHD device that is in operation at NIFS.

Bilja stayed at ENEA Frascati Research Center for two weeks

As a part of the realisation of NOVA2LIBS4fusion project, Biljana had a scientific stay at the ENEA Frascati Research Center. There she had the opportunity to collaborate directly with Dr. Violeta Lazić, where they performed LIBS experiments and the analysis of the experimental results is underway.

Milica gave a lecture on 17th Photonics Workshop

17th Photonics Workshop was held from 10th – 14th March at the Ski Resort Kopaonik. Milica was invited to give a lecture on her work on diagnostics of Laser Induced Plasma from thin oil film. The talk was entitled Diagnostics of laser-induced plasma from a thin oil film.

New publication by Ivke, Bilja and Ivan

During the work on the realization of NOVA2LIBS4fusion project financed by the Science Fund of the Republic of Serbia Ivke, Bilja and Ivan published an article in Spectrochimica Acta B: Atomic Spectroscopy journal entitled LIBS depth-profile analysis of W/Cu functionally graded material

Ivan became Research Assistant

We proudly announce that since 7th November 2022., Ivan has a new scientific title of Research Assistant at the Insitute of Physics Belgrade. We wish him a lot of success in his research in the years to come.

Milica presented the results from her PhD thesis on IX International School and Conference on Photonics

IX International School and Conference on Photonics was held in Belgrade from 28th August to 1st September. Milica was invited to give a progress report on her work on application of LIBS in determination of trace metals in oils. The talk was entitled Application of laser-induced breakdown spectroscopy for the determination of trace metals in oils.

Ivan took part in this year ITER International School held in Aix – en – Provence

It is our great pleasure to report that Ivan was accepted to participate in this year ITER International School 2023. The topic of the summer school was Energetic Particles in Fusion Plasmas, where the school gathered leading experts in this filed that gave lectures to the students. Part of the summer school was also dedicated to the visit of ITER site, where students had the opportunity to see the site and to hear recent advances in the construction of the largest tokamak so far.

Ivan presented part of his PhD thesis work on 14th SCSLSA

14th SCSLSA was held in Bajna Bašta from 19th to 23rd June. Ivan was invited to give a progress report on his wok on application of Machine Learning algorithms on the determination of Stark Broadening line widths. The talk was entitled Stark Broadening Modeling with ML and AI Algorithms and abstract is given below.

During past 20 years many Stark broadening models were developed that can calculate spectral lineshape and estimate a line width that is extensively used in plasma diagnostics of both astrophysical and laboratory plasmas. Some of these calculations yield results relatively fast, some of them need a lot of computational time. Therefore, idea of creating a machine learning (ML) model emerged as a tool for fast estimation of Stark width without need of huge computational time. In our approach, out of three tested models, random forest (RF) algorithm showed the best predictive power after it has been trained, where the coefficient of determination R2 = 0.94 was obtained. Model was trained on a database created by merging parameters from Stark B and NIST atomic databases, it had 14 input parameters that were used to predict final Stark width. Results were compared with experimental ones as well as with SCP theory. We also checked for regularities in Stark effect, and they were also confirmed and in agreement with previous findings.

Ivan took part in scientific excursion organised by Faculty of Physics

From 29th May until 3rd June Ivan took part in scientific excursion jointly organised by Faculty of Physics of University of Belgrade and Physical Society of Serbia. Firstly they visited Electrotechnical Faculty of University of Brno, where they saw Laboratory for High Voltages and High Currents.

Next they visited Institute of Plasma Physics of Czech Academy of Sciences and Arts where they had a lecture given by prof. Jan Horacek from IPP about fusion and tokamak physics in general. This was followed by the tour through PALS laboratory, where they saw a PW iodine laser system.

The next day they went to Dresden, to visit Helmholtz Zentrum Dresden – Rossendorf scientific institute, where they had opportunity to see free – electron laser system located at ELBE facility, as well as PW laser system DRACO that was recently put in operation.

At the end, they were guests in ELI beams facility, where they saw the most powerful laser systems in the world and had pleasure of hearing interesting lectures from experts employed there.

Nenad published new article

We are pleased to announce that Neša, together with his collaborators, has published new article entitled The significance of applying different factors for the evaluation of sediment contamination by toxic elements and estimation of the ecological risk in Environmental Science and Pollution Research.
