Multiscale non-adiabatic dynamics with radiative decay, case study on the post-ionization fragmentation of rare-gas tetramers
In this supplementary material, we recollect, for reader's convenience, the
general scheme of suggested multiscale model (Sec. 1), and basic informations
about approaches used for pilot study: a detailed description of the
interaction model (Sec. 2) and dynamical methods used for the dark dynamics
step (Sec. 3) reported previously in two preceding studies [1, 2]. In addition,
a detailed description of the treatment of radiative processes is also given
(Sec. 4).Comment: supplementary material for parent paper; 9 pages, 1 figure; corrected
formulae and misleading notation in Sec.4 (pages 7 and 8
Hypergravity effects on glide arc plasma
The behaviour of a special type of electric discharge â the gliding arc plasma â has been investigated in hypergravity (1g â18g) using the Large Diameter Centrifuge (LDC) at ESA/ESTEC. The discharge voltage and current together with the videosignal from a fast camera have been recorded during the experiment. The gliding of the arc is governed by hot gas buoyancy and by consequence, gravity. Increasing the centrifugal acceleration makes the glide arc movement substantially faster. Whereas at 1g the discharge was stationary, at 6g it glided with 7 Hz frequency and at 18g the gliding frequency was 11 Hz. We describe a simple model for the glide arc movement assuming low gas flow velocities, which is compared to our experimental results
