A high harmonic cavity (HHC) with a certain phase modulation frequency can increase the longitudinal emittance and smooth the density distribution within a particle bunch. Such a cavity helps to prevent particle losses during passage through the transition energy. The speed of dilution and the quality of density redistribution depend on the phase modulation program. In this report, we show how to choose such a program which will create traveling waves which push the front of high density from the center of the bunch to its boundary. Supporting results from machine and computer experiments are presented. 4 refs., 3 figs.
