Density control via real-time variation of pellet mass and frequency
2025 Research Campaign, Plasma Control
Purpose of Experiment
This experiment seeks to optimize density control throughout an evolving discharge, by fully leveraging the degrees-of-freedom available to ITER/FPP-relevant actuators, by controlling both the pellet mass and frequency.
Experimental Approach
This experiment will exploit a new capability to adjust the size of fueling pellets on DIII-D, to optimize density control throughout an evolving discharge by controlling the pellet mass in real time.
