| Research Abstract |
The removal process of oxide layer in the vacuum arc using high speed spectroscopic measurement was elucidated by using the 2D high speed spectroscopic measurement system with beam splitter and band path filter and plasma image processing developed by this research representative. It is expected that the method of high speed oxide layer removal is obtained from this elucidation. Concretely, the removal process such as stagnation time, track, and species of vapor at oxide layer removal is elucidated with the above method, and then, the condition for fast oxide layer removal is elucidated. As a result, it takes a time for removing the oxide layer, and this time depends on the specific heat and thermal conductivity. Thus, the appropriate vapor amount value of stagnation time is important to maintain and move the vacuum arc. This technology with the knowledge for development of method of high speed removal process of oxide layer will be applied for the social needs of 3R.
