Large-scale particle-in-cell plasma simulations on modern supercomputers often involve handling immense amounts of macroparticles, which poses a challenge in terms of computational and memory resources.
Furthermore, the amount of macroparticles could grow throughout a simulation due to accounting for such processes as ionization or creation of electron-positron pairs. In such situations, a...

Traveling-Wave Thomson-Scattering (TWTS) is a novel Thomson scattering geometry which allows for orders of magnitude higher photon yields than classic head-on Thomson sources. TWTS thereby remains compact and provides narrowband and ultra-short ultraviolet to γ-ray radiation pulses just as classic Thomson sources. Even the realization of optical free-electron lasers is possible with the TWTS...
