Particle charge in PK-4 dc discharge from ground-based and microgravity experiments
T. Antonova, S. A. Khrapak, M. Y. Pustylnik +6
The charge of microparticles immersed in the dc discharge of the Plasmakristall-4 experimental facility has been estimated using the particle velocities from experiments performed…
Unified description of sound velocities in strongly coupled Yukawa systems of different spatial dimensionality
Sergey Khrapak
Sound velocities in classical single-component fluids with Yukawa (screened Coulomb) interactions are systematically evaluated and analyzed in one-, two-, and three spatial dimensi…
Single-crystal and polycrystalline diamond erosion studies in Pilot-PSI
D. Kogut, D. Aussems, N. Ning +9
Diamond is a promising candidate for enhancing the negative-ion surface production in the ion sources for neutral injection in fusion reactors; hence evaluation of its reactivity t…
Modified Frost formula for the mobilities of positive ions in their parent gases
S. A. Khrapak, A. G. Khrapak
A modification to the semi-empirical Frost formula for the mobilities of singly charged positive ions in their parent gases is proposed. The modified expression demonstrates excell…
Theory of a cavity around a large floating sphere in complex (dusty) plasma
S. Khrapak, P. Huber, H. Thomas +2
In the last experiment with the PK-3 Plus laboratory onboard the International Space Station, interactions of millimeter-size metallic spheres with a complex plasma were studied~[M…
Particle dynamics in deposition of porous films with a pulsed radio-frequency atmospheric pressure glow discharge
Y. Xu, S. A. Khrapak, K. Ding +4
Nanoparticles grown in a plasma are used to visualize the process of film deposition in a pulsed radio-frequency (rf) atmospheric pressure glow discharge. Modulating the plasma mak…
