Plasmoid instability in the semi-collisional regime
<|begin_of_text|><|start_header_id|>system<|end_header_id|> You are a research archivist expert in dataset metadata. Answer the question truthfully.  <|eot_id|><|start_header_id|>user<|end_header_id|> Here is the Description of a dataset. Description:'We investigate analytically and numerically the semi-collisional regime of the plasmoid instability, defined by the inequality δSP ≫ ρs ≫ δin, where δSP is the width of a Sweet-Parker current sheet, ρs is the ion sound Larmor radius, and δin is width of boundary layer that arises in the plasmoid instability analysis. Theoretically, this regime is predicted to exist if the Lundquist number S and the length of the current sheet L are such that (L/ρs ) 14/9 < S < (L/ρs ) 2 (for a sinusoidal-like magnetic configuration; for a Harris-type sheet the lower bound is replaced with (L/ρs ) 8/5 ). These bounds are validated numerically by means of simulations using a reduced gyrokinetic model (Zocco & Schekochihin, Physics of Plasmas 18, 2011) conducted with the code Viriato.
