The idea of controlling the plasma flows in laser targets by action of
a strong external magnetic field (H greater than or equal to 1 MG) is
presented. The magnetic control of plasma flows for the keeping of a
transparency of entrance holes of indirect-compression targets and oth
er type targets operating at an introduction of the laser beams into t
he interior of the target is suggested. It is shown that the magnetic
field, transverse versus the direction of the propagation of the plasm
a flow with an intensity of 2-4 MG, causes a decrease (1.5-3 times) of
the dosing speed of holes for the laser beam introduction into the ho
hlraum target.
