The data set for "Measurement of velocity and reliability of 50 Hz pellet injector for EAST"

A high frequency, 50 Hz, pellet injection system (PI-50) based on screw extrusion forming ice and pneumatic acceleration has been built and developed for ELM mitigation for EAST. As velocity and reliability of launching frozen pellet are of importance to ELM mitigation, a diagnostic system including video cameras is installed on this pellet injection system to acquire the pellet's velocity and monitor the quality of pellet. With the help of this diagnostic system, the velocity and reliability of PI-50 system have been measured successfully. This data set contains the main data supporting the above points.
