  Methods of plasma heating by electromagnetic waves, interaction of
electro-magnetic waves with magnetoactive plasma, plasma turbulence and
transport processes are investigated in the trap of the linear plasma device
OMT2. An ultrahigh frequency (UHF) contactless method is used to fill the open
magnetic trap by plasma. We propose a new method of open magnetic trap filling
with plasma whereby plasma is injected in the trap along the magnetic field
from an independent stationary UHF source. The source is located outside the
trap and plasma formation in it takes place in the strongly nonuniform magnetic
field, in the electron cyclotron resonance (ECR) regime by means of the UHF
power. In this paper we study the efficiency of open magnetic trap filling by
plasma and plasma low frequency (LF) oscillations in the trap.
