Data set for "Construction and experimental tests of the high frequency pellet injection system on EAST tokamak"
Listed in ScienceDB
A high frequency deuterium pellet injection system based on extrusion and pneumatic acceleration has been recently developed and built for EAST tokamak, which is one of fully superconducting Tokamaks with ITER-like plasma configuration.
Description
It is mainly used for plasma edge localized mode control and can achieve 1–50 Hz injection rate. It has been completely installed on EAST up to now.
A new differential pumping system and pellet transmission lines have been designed according to the actual condition of EAST. Recently we have tested thesystem systematically and injected multiple pellets into type-I ELMy H-mode plasma on EAST for the first time. The test and experimental results show that the system can inject continuous pellets into plasma stably, and ELMs can be triggered by deuterium pellets in H-mode plasma with negligible impact on density and stored energy.

And it was also found that ELM trigger efficiency is less than 100 % sometimes. The data set contains the main the main data supporting the above points.
