参加報告：Joint international experiment at the ELI-Beamlines User Facility (Dr. Pirozhkov)

量子科学技術研究開発機構 関西光科学研究所のAlexander Pirozhkov氏がチェコのドルニー・ブルジェジャニのELI-Beamlines User Facilityでの国際共同実験に参加されました。

以下、Alexander Pirozhkov氏の報告になります。

I  led a joint international experiment at the ELI-Beamlines User Facility with participation of research groups from KPSI QST (Japan), Hiroshima University (Japan), National Taiwan University (Taiwan), Institut für Nanophotonik (Germany), and ELI-Beamlines (Czech Republic). We used the ALFA Facility (ALFA Laser-Plasma Accelerator) driven by the multi-TW kHz L1 ALLEGRA laser to generate coherent XUV radiation by the Burst Intensification by Singularity Emitting Radiation (BISER) mechanism. We obtained promising results and contributed to the ALFA Facility development by introducing the full-power in-vacuum focal spot measurement, installing a very stable full-power on-shot beam monitor, establishing a semi-automatic and automatic Machine-Learning-based OAP alignment method, and developing Machine Learning software to automatically optimize experimental XUV yield.
There were other interesting events happening during our experiment, such as visit of Queen Máxima of the Netherlands and Czech President Petr Pavel to ELI-Beamlines, and more, however, I missed them as I stayed mostly in the lab.

滞在中に、オランダのマキシマ王妃とチェコ共和国大統領ペトル・パベルがELI-Beamlinesを訪問されたそうですが、Pirozhkov氏はお姿見逃したそうです。訪問の様子はこちら
