Doctoral Candidates (DCs)

The physics that describes negative ions is largely unknown, mainly due to technical difficulties in their investigation and detection. The PANIONS program aspires to overcome these problems with a series of research in various areas of negative ions. Perhaps the most important step in this effort is the collaboration of groups that are pioneers in negative ion research with large research infrastructures. It is a great opportunity to unlock this important part of physics, as any experimental studies are supported for the first time by modern theories. Negative ions can have countless useful applications in our lives. The involvement of industries that will transfer the significance of the findings to the real world is another strong advantage of this program.

DC3: Inner-shell photodetachment of atomic and molecular anions

Justus Liebig University Giessen (JLUG)

My journey into the world of physics began in 2018. It was the year I was admitted to the physics department of the University of Ioannina. Upon completing the compulsory courses, I decided that I wanted to pursue the field of experimental physics with a specialization in atomic physics. During my undergraduate studies, I completed my thesis entitled “Design of a VMI homogeneous electric field spectrometer”, where I designed a new spectrometer for slow electrons.

After graduating from the undergraduate program in 2022, I was accepted to the postgraduate program of the University of Ioannina, where I followed the field of experimental physics and got my MSc in Physics in 2024. During this two years program, I completed my Master thesis on “ Electron spectroscopy using hemispherical and toroidal spectrometers”. Most of the experiments were held at “NCSR Demokritos” in Athens, where I managed to get valuable experience on accelerators. During all these years, I attended conferences, summer schools and international programs, such as the international student program of GSI, getting experience on the fields of accelerator physics and laser physics. My motivation was to learn more, not only about atomic physics, but for every aspect of a complete experiment procedure.
