We present the results of investigations by grazing incidence neutron reflectometry of supermirrors NiC/Ti. Their effective critical angle is 1.9 times the critical angle of natural nickel. With these supermirrors, a curve neutron guide has been installed in the neutron guide hall of the ORPHEE reactor. This guide, called G5bis, has a radius of 155 m. The total flux measured at the guide exit is 1.22 10<SUP>9</SUP> n.cm<SUP>-2</SUP>.s<SUP>-1</SUP>. the layout and performances of the new guide are compared to the guide G5 and to a classical multichannel bender.
