Setup for Studying Vortex Flow on the Surface of a Liquid 4He Layer in Normal and Superfluid States

The design of a setup intended for studying the interaction features of vortex flows generated by capillary-gravity waves on the surface of liquid helium ⁴He in normal and superfluid states with injected charges is described. An example of the results of studying the influence of vortex flows generated by waves in a layer of superfluid helium He-II with a depth of 2.5 cm at temperatures T ≥ 1.5 K for the distribution of negative ion currents across five segments of a receiving collector immersed in liquid is given.
