| Research Abstract |
In-liquid plasma evaporates a surrounding liquid by their heat and generates bubbles. As to the 27. 12MHz high frequency underwater plasma in 10-101kPa, simultaneous observation of two plasma emission distributions or a plasma emission distribution and bubble behavior was performed by assembling a high-speed camera and optical systems, such as a dichroic mirror. Excitation temperature distribution was calculated from two distributions of plasma emission. The periodicity of the cycle of the growth and the departure of bubble became more regular with the increase in a pressure. Just before the departure of the bubble the temperature in the bubble which was stretched between the electrode and the rising bubble was found to reach the maximum.
