SPIG 2022
Ivke, Biljana, Neša, Milica and Ivan participated in 31th Symposium of Physics of Ionized Gases (SPIG 2022), held in Belgrade at the Serbian Academy of Sciences and Art. The conference was organized in hybrid format, part of the lectures was online and the other part was on site. Ivke was member of the Scientific Committee for the fifth consecutive time. Neša was in the Ogranizing Committee.
At the poster presentation part of the conference, Biljana presented the poster entitled “Spectroscopic characterization of laser-induced plasma on doped tungsten“, while Ivan presented the poster entitled “Elemental analysis of austenitic steel by calibration-free laser-induced breakdown spectroscopy (CF-LIBS)“. Apart from this, we also presented, or participated in the following posters:

Application of artificial neural network in the analysis of the spectra from laser ablation combined with fast pulse discharge – Nenad M. Sakan, Milica L. Vinić, Vladimir A. Srećković, Ivan Traparić, and Milivoje R. Ivković
Modeling of Stark spectral line broadening by machine learning algorithms – Irinel Tapalaga, Ivan Traparić, Nora Trklja Boca, Jagoš Purić and Ivan P. Dojčinović
LIBS 2022 Bari
Ivke, along side with prof. Miroslav Kuzmanović and prof. Jelena Savović participated at international LIBS 2022 conference held in Bari to present recent results obtained through the project IDEAS, financed by Science Fund of the Republic of Serbia.
Ivke presented a poster entitled LIBS analysis of tungsten – copper alloys while prof. Savović held the invited talk entitled Relevance of mid-infrared laser as an excitation source for a variety of LIBS applications.
SPIG 2020
Ivke, Biljana and our MSc student Ivan Traparić participated in this year’s jubilee 30th Symposium of Physics of Ionized Gases (SPIG 2020). Because of the bad situation in Serbia due to Coronavirus pandemic, SPIG 2020 was organized completely in online format. The honor to give the introductory talk had Acad. Prof. dr Zoran Petrović. Ivke was member of the Scientific Committee for the forth consecutive time. Also, Ivke chaired the Thursday’s mourning Plenary Session.
At the poster presentation part of the conference, Biljana presented the poster entitled “Appearance of Be II 436.1 nm line with forbidden component in LIBS plasma”, while Ivan presented the poster entitled “VUV Spectroscopy of the He II – Lyman Series for electron density estimation”.
We are also proud to announce that we invited five lecturers. First, Tony Donne, the Programme Manager of EUROfusion and head of the Fusion Physics Division at the Dutch Institute for Fundamental Energy Research (DIFFER) gave the plenary talk “Challenges and Progress on the Path Towards Fusion Electricity”. Second, Sibylle Günter, Scientific Director of IPP (Max Planck Institute for Plasma Physics) gave the plenary lecture “The Two Conceps of Magnetic Confinement: Tokamak and Stellerator”. Third invited lecturer was Dimitri Batani from University of Bordeaux, who was invited to held the lecture at 1st BegFust (Belgrade Fusion Science and Technology Workshop), which was unfortunately postponed. Nevertheless, prof. Batani held the plenary lecture entitled “Current Status of the Laser Fusion Research and the Shock Ignition Approach”. Fourth invited lecturer was Sebastian Brezinsek from Forschungszentrum Jülich, Institute of Energy and Climate Research, who gave the topical invited lecture “Plasma-Wall interactions in Wendelstein 7-X Operating with Graphite Divertor”. Fifth invited lecturer was Daiji Kato from NIFS (National Institute for Fusion Science) Japan, who gave the topical invited lecture entitled “Compact Electron Beam Ion Trap for Spectroscopy of Multiple Charged Ions“.
Ivke visit to NIFS in Japan
From 27th October to 4th November 2019 Ivke visited NIFS (National Institute for Fusion Science) in Toki, Japan, as a member of University of Belgrade delegation headed by rector Ivanka Popović, who signed an Agreement of collaboration between NIFS and University of Belgrade.
Ivke, Bratislav Obradović (Faculty of Physics), Milan Rajković (Institute of Nuclear Sciences Vinca) and Milica Ilić (Faculty of Mechanical Engineering) had a fruitful discussions with Japanese colleagues and made plans for future common projects.
Seminar by Ivke and Miloš
On 9th September 2019 Ivke and Miloš held a seminar in the Library “Dr. Dragan Popović” at the Institute of Physics in Belgrade. Ivke had spoken about the topic “Lasers, Laser Produced Plasmas and Optical Emission Spectroscopy”. Shortly after Ivke, Miloš gave the lecture “VUV Spectroscopy of Fusion Plasmas”.
Scientific Trip by Ivke across Central Europe
Ivke participated in Scientific Excursion organized by Physical Faculty, Society of Physicist of Serbia and ETA Turs from 27th May until 1st June 2019.
He visited:
- ELI attosecond in Szeged (HU);
- High voltage laboratory in Brno (CZ), where they work with 120 kA currents and 2 MV voltages;
- Helmholtz‐Zentrum Dresden‐Rossendorf in Dresden (D) seeing Ion Beam Facility and Radiation Source ELBE;
- ELI beams and Institute of Plasma Physics in Prague (CZ), latter one showed him COMPASS tokamak and PALS ion laser.
Biljana’s new publication
We are proudly presenting published article by Biljana, her second article this year as the first author. However, the significant contribution of co-authors should not overseen. The article is entitled “Forbidden component of the Be II 436.1 nm line recorded from pulsed gas discharge plasma” and published by Europhysics Letters journal.
Lecture by our Guest
Yesterday, the Laboratory hosted Dr. Predrag Ranitović, who held an open lecture at Institute of Physics Belgrade. The lecture title was “Attosecond Coherent Control of Atomic and Molecular XUV and X-Ray Absorption Processes by Intense Laser Radiation”.
Abstract:
Recent breakthroughs in the ultrafast lasers development have allowed for the opening of new horizons in the ultrafast experimental and theoretical AMO physics. Following these advances, table-top light sources have provided novel ways to achieve a real-time manipulation of the correlated electron/nuclear wavepacket dynamics by means of attosecond XUV and femtosecond IR radiation [1-6]. However, more than fifteen years upon the birth of attosecond physics, and after the Nobel Prize Award for femtochemistry, the concept of attosecond chemistry has not yet been fully realized. In this talk, I will introduce the basic principles of the strong laser-field ionization and generation of attosecond XUV/X-Ray radiation, and show how the attosecond VUV and XUV light sources can be used to coherently manipulate molecular dynamics by means of electron wave packet interferometry [7-9]. The use of attosecond VUV pulse-trains to coherently excite and control the outcome of a simple chemical reaction in a deuterium molecule, in a nonBorn-Oppenheimer regime, presents intriguing new possibilities for bridging the gap between the attosecond physics and attochemistry [10]. Furthermore, I will discuss very recent results that extend the use of the attosecond table-top techniques to the soft X-Ray regime in the water window [11].
