Research Abstract |
The structure formation of atmospheric millimeter wave breakdown plasma was observed. The atmospheric millimeter-wave breakdown was observed under various beam profiles. Several profiles were produced from a high-power 170GHz gyrotron beam using the beam mode converter. The breakdown plasma had unique structure depending on each beam profile. The structure was determined by the trajectory of ionization spots depending on beam profile. The breakdown threshold under various gas species condition was also observed.
