Description

Videos show grains through a long-distance microscope camera, recorded at 1200 fps, through a Phantom v640 camera. The frame size is approximately 3.3 x 5mm. 

The plasma is switched off for a 50 ms period, and grains suddenly move downward due to the local temperature gradient. When the plasma is restored, they rebound to their initial positions. 

This data is used in our study to obtain the terminal velocity of grains in the plasma afterglow. The main manuscript can be retrieved at https://doi.org/10.1103/rx5l-k7f9
