Senior Postdoctoral Researcher | Atomic and Molecular Physics | Attosecond Physics, Experimental Research
We are pleased to announce that our manuscript entitled "Energetic, tunable, highly elliptically polarized higher harmonics generated by intense two-color counter-rotating laser fields" by E. Vassakis, S. Madas, et al." was accepted for publication in Physical Review A. This manuscript presents our experimental and theoretical effort on the development of the most energetic highly-elliptical polarized HHG beamline. This beamline was developed in Attosecond Science and Technology Laboratory (AST) of IESL-FORTH in Greece. The theoretical support was provided by the theory division of ELI-ALPS in Hungary and to be more specific by the group of Dr. Mousumi Upadhyay Kahaly. This new beamline developed in AST has unique characteristics. It provides the generation of tunable highly elliptical XUV radiation (17-26 eV) with controlled polarization, reaching energies at the range of 400 nJ at the source. This is the highest energy content ever achieved in the generation of laser driven circularly polarized XUV radiation. These ellipticity values in conjunction with the high energy content of the XUV pulses, reveal a source adequate for applications like control and imaging of ultrafast magnetism in magnetic materials, in ultrafast chiral matter investigations and also in the investigation of circular dichroism in atomic systems where intense highly-elliptical/cicrcularly polarized XUV radiation is necessary for inducing nonlinear processes. https://lnkd.in/dwAy6q-A

📃Scientific paper: Have pulsar timing array methods detected a cosmological phase transition? Abstract: We show that the recent detection of a gravitational wave \(GW\) background reported by various pulsar timing array \(PTA\) collaborations including NANOGrav-15yr, PPTA, EPTA, and CPTA can be explained in terms of first order phase transitions \(FOPTs\) from dark sector models \(DSM\). Specifically, we explore a model for first order phase transitions that involves the majoron, a Nambu-Goldstone boson that is emerging from the spontaneous symmetry breaking of a $U\(1\)\_\{L\}$ or $U\(1\)\_\{B-L\}$ symmetry. We show how the predicted GW power spectrum, with a realistic choice of the FOPT parameters, is consistent with 1-$\sigma$ deviations from the estimated parameters of the background detected by the PTA collaborations. ;Comment: 4 pages, 1 figure Discover the rest of the scientific article on es/iode ➡️https://etcse.fr/8Kt

📚 Exciting New Publication Alert! 🚀 I'm thrilled to share our latest research, titled "Monte Carlo simulation for proton dosimetry in magnetic fields: Fano test and magnetic field correction factors kB for Farmer-type ionization chambers." You can read the full article here: https://lnkd.in/eN-yK2st 🔬 In this study, we developed a special Fano test for charged particles in the presence of magnetic fields using the MC code TOol for PArticle Simulation (TOPAS). We also determined magnetic field correction factors (k_B) for Farmer-type ionization chambers with proton beams. 🚀 Key Findings: - TOPAS successfully passed the Fano test for both electrons and protons in presence and absence of magnetic fields. - The chamber response (k_B,M,Q) depends on the chamber size and magnetic flux density, with local dose differences remaining minimal. - The magnetic field correction factor (k_B) for the PTW 30013 chamber ranged from 0.9946 to 1.0036 for both tested energies. - This work marks a significant advancement in proton dosimetry in presence of magnetic fields, contributing to the development of MR-guided proton therapy. 🌟 Our research extends the capabilities of TOPAS as a valuable tool for determining k_B and represents the first calculations of k_B for proton beams. I want to extend my heartfelt thanks to my co-authors for their invaluable contributions from the very beginning of this publication. 🙌 Thank you to all the collaborators and supporters who made this research possible. Your dedication and contributions are truly appreciated. Feel free to dive into the details by clicking the link above. If you have any questions or would like to discuss the findings further, please don't hesitate to reach out. 🌐💡 #Research #ProtonDosimetry #MagneticFields #MRgPT #MRinRT #MRguidance #Protontherapy #TOPAS #ScienceAdvances

PhD Candidate @Fohtung Research Group RPI| COEP 2020 | Operando Manipulation and Characterization of Functional Materials with Twisted Photons
🎉 Exciting News! I'm happy to share that I had the opportunity to present my latest research at the 67th Annual Conference on Magnetism and Magnetic Materials 2023. 🎙📊 During the presentation, I discussed use of Operando Bragg Coherent Diffractive Imaging(OBCDI) to manipulate and characterize topological defects using magnetic fields. We used the facilities at Argonne National Laboratory, Advance Photon Source, 34 IDC for this experiment. It was inspiring to engage with fellow researchers and professionals who share a passion for Magnetism and Magnetic Materials. 🤝 🔍 Key Takeaways: • Successful manipulation of topological defects in multiferroic Barium Hexaferrite nanoparticles using Magnetic Fields • Three dimensional characterization of Topologies in nanoparticles • An asymmetric butterfly loop of strain vs magnetic field which is of immense importance in several applications. I want to express my gratitude to my advisor Prof Edwin Fohtung, my colleague Sowmya Srinivasan, and beamline scientist Dr. Ross Harder whose support made this research possible. 🙏 📣 I encourage you to check out the conference proceedings and explore the diverse range of topics covered by my fellow presenters. Let's continue pushing the boundaries of knowledge together! https://lnkd.in/gThZVt56 #materialsscience #materialsengineering #materialsresearch #materialcharacterization #conference2023 #conferencepresentation

A team of scientists from Ernst Ruska-Centre (ER-C), RWTH Aachen University and DTU - Technical University of Denmark including Prof. Knut Urban, Prof. Joachim Mayer and Prof. Joerg R. Jinschek had reported energy-filterted EELS mapping using an EFTEM with electrons exhibiting Si L₂,₃ core losses which yielded an elemental distribution maps of the specimen at atomic spatial resolution. Because of EFTEM, the analysis can be referred to as achromatic elemental mapping. The experiments were performed on PICO Cc/Cs corrected Thermo Fisher Scientific Titan 60–300 microscope at Ernst Ruska Centre operated at 300 keV and equipped with a C-COR Cc/Cs image corrector. Read the exciting paper published in PRL. https://lnkd.in/d9kWzCZA #EFTEM #PICO #sphericalaberrations #chromaticaberration #Cscorrection #Cccorection #imagecorrection #atomicresolution #electronmicroscopy

As we can see in our ordinary live, the the theory needs to be adjusted with an experimental part. As a consequence of the hard work at CERN #LHC, experimental data from #CMS and #ATLAS are showing a behavior of the desintegration on the Higgs' Boson that differs from the standard model and could be explained by the ongoing research about supersimmetry. The Next chapter of this research should be really interesting. Let's wait for It ;) and congrats to the researchers Who wrote this paper.

Oh the old days! This is a photo from October 1968. It was work like this that inspired many to look deep into science from the subatomic to the planets and beyond. It is part of ISOLDE (Isotope Separator On-Line Device) Radioactive Ion Beam (RIB) Facility. An isotope separator facility located at CERN's first ever particle accelerator. From the control desk on the left, the proton beam from the particle accelerator could be monitored and the performance of the target and separator controlled. The ion beam containing the isotopes entered through the wall and was analyzed in the magnet. One of the beams could then be transported to the detectors. At the end of the pipe, on the right, was a tape system for collecting the isotopes. Isotopes became embedded in the tape and detectors could be brought to the tape for measurements, an electron detector⁴, above, and a gamma detector⁵, below, could be brought into position. That year, a system was being developed to make it possible to switch the ion beam to three users, increasing the number of experiments which could be performed simultaneously with ISOLDE.
