Query: Experimental investigation of coaxial-gun-formed plasmas injected into a
  background transverse magnetic field or plasma   Injection of coaxial-gun-formed magnetized plasmas into a background
transverse vacuum magnetic field or into a background magnetized plasma has
been studied in the helicon-cathode (HelCat) linear plasma device at the
University of New Mexico [M. Gilmore et al., J. Plasma Phys.81, 345810104
(2015)]. Magnetized plasma jet launched into a background transverse magnetic
field shows emergent kink stabilization of the jet due to the formation of a
sheared flow in the jet above the kink-stabilization threshold $0.1kV_A$ [Y.
Zhang et al., Phys. Plasmas 24, 110702 (2017)]. Injection of a spheromak-like
plasma into a transverse background magnetic field led to the observation of
finger-like structures on the side with a stronger magnetic field null between
the spheromak and background field. The finger-like structures are consistent
with magneto-Rayleigh-Taylor instability. Jets or spheromaks launched into a
background, low-$\beta$ magnetized plasma show similar behavior as above,
respectively, in both cases.
