The operation peculiarities and performance of new millimetric noise source on BWO are described. To increase the interaction efficiency and to extend the operation frequency band the modified vane-type slow-wave structure is proposed to use. Packaged Ka -band source provides noise with power spectrum width controlled within 10 - 300 MHz, electronic tunability of the frequency of 10-12 % and has the output power up to 18W and electronic efficiency of 5.5 %. Electronic tuning of noise frequency has a discontinuities, but the operation frequency band is almost fully covered. To have a possibility to tune the noise power spectrum maximum to the desired frequency both the electronic tuning and mechanical one can be used. Application of the magnet system with focusing magnetic field magnitude up to 4300 G allows to increase output power level and electronic efficiency up to 32 W and 7 % respectively.
