What happens and what is left?

1. Pump power vs Time

2. The results

3. Sudden power increase

  1. Quick rise in plasma temperature
  2. Delayed void inflation due to high viscosity of the surrounding melt
  3. Void formation is suspended until the recovery of equilibrium state


4. Sudden power decrease

  1. Quick drop in plasma temperature
  2. Delayed void deflation makes its tail frozen to extend the whole void.
  3. (same as above)
