A plasma photocathode for spin-polarized electron beams via state-selected hydrogen halide photofragments
Lars Reichwein, Thomas C. Wilson, Dimitris Sofikitis +6
Spin-polarized electron beams are essential tools for probing fundamental symmetries and for the search beyond the Standard Model. While plasma-based accelerators are a promising p…
Report on the Advanced Linear Collider Study Group (ALEGRO) Workshop 2026
L. Verra, P. Muggli, B. Cross +56
The 7th ALEGRO workshop, hosted by INFN Frascati National Laboratories from 3rd to 5th March 2026, brought together the international Advanced Novel Accelerators (ANA) community to…
Pinching injection in wakefields for spin-polarized electron beams
Lars Reichwein, Dimitris Sofikitis, Oliver Mathiak +5
Pinching of the driver beam in plasma wakefield acceleration is generally considered an unwanted effect that needs to be mitigated. Here, we propose that this effect can be utilize…
High-energy polarized electron beams from the ionization of isolated spin polarized hydrogen atoms
Dimitris Sofikitis, Lars Reichwein, Marios G. Stamatakis +5
We propose a laser-based method for the preparation of high-energy polarized electrons, from the ionization of isolated spin-polarized hydrogen (SPH) atoms. The SPH atoms are prepa…
Polarized Proton Beams from Laser-induced Plasmas
Anna Hützen, Johannes Thomas, Jürgen Böker +7
We report on the concept of an innovative source to produce polarized proton/deuteron beams of a kinetic energy up to several GeV from a laser-driven plasma accelerator. Spin effec…
Ultrahigh-density spin-polarized H and D observed via magnetization quantum beats
Dimitris Sofikitis, Chrysovalantis S. Kannis, Gregoris K. Boulogiannis +1
We measure nuclear and electron spin-polarized H and D densities of at least 10 with 10 ns lifetimes, from the photodissociation of HBr and DI with circularl…
Highly spin-polarized deuterium atoms from the UV dissociation of Deuterium Iodide
D. Sofikitis, P. Glodic, G. Koumarianou +5
We report the production of highly spin-polarized Deuterium atoms via photodissociation of deuterium iodide at 270 nm. The velocity distribution of both the deuterium and iodine ph…
Evanescent-wave and open-air chiral sensing via signal-reversing cavity-enhanced polarimetry
Dimitris Sofikitis, Lykourgos Bougas, Georgios E. Katsoprinakis +3
Sensing chirality is of fundamental importance to many fields, including analytical and biological chemistry, pharmacology, and fundamental physics. Recent developments have extend…
Molecular vibrational cooling by Optical Pumping with shaped femtosecond pulses
Dimitris Sofikitis, Sebastien Weber, Andréa Fioretti +5
Some of us have recently reported in Science 321 232 (2008) vibrational cooling of translationally cold Cs_2 molecules into the lowest vibrational level v=0 of the singlet X 1Sigma…
