  We present a new powerful liquid hydrogen target developed for the precise
study of parity violating electron scattering on hydrogen and deuterium. This
target has been designed to have minimal target density fluctuations under the
heat load of a 20$\mu$A CW 854.3 MeV electron beam without rastering the
electron beam. The target cell has a wide aperture for scattered electrons and
is axially symmetric around the beam axis. The construction is optimized to
intensify heat exchange by a transverse turbulent mixing in the hydrogen
stream, which is directed along the electron beam. The target is constructed as
a closed loop circulating system cooled by a helium refrigerator. It is
operated by a tangential mechanical pump with an optional natural convection
mode. The cooling system supports up to 250 watts of the beam heating removal.
Deeply subcooled liquid hydrogen is used for keeping the in-beam temperature
below the boiling point. The target density fluctuations are found to be at the
level 10$^{-3}$ at a beam current of 20 $\mu$A.
