The results of experimental researches of spatio-temporal descriptions of radiation of negative crown are presented in the mode of impulses of Trichela in mid air. It is shown that for electrode geometry a «needle-sphere» along with a radiation from neighbouring of sharpen electrode exists radiation from a anode area. It is set that intensity of radiation from a anode area depends on the form of anode. A radiation from every electrode area takes impulsive character. A radiation from a anode area is observed time-lagged after the beginning of impulse of bit current. It is set that duration of this delay depends on length of bit interval and size of the attached tension. It is shown that correlation of amplitudes of impulses of radiation from cathode and anode areas also depends on the size of the attached tension.
Keywords: negative crown, impulse of Trichela, radiation, drift area, anode area, wave of indignation, form of anode
