Simultaneous pellet injection observed to impact disruption mitigation metrics compared to single pellet injection in DIII-D. Multiple shattered pellets injected for the first time as planned for ITER Effect of multiple pellets appears to not sum directly in DIII-D plasmas. expected.

Simultaneous pellet injection observed to impact disruption mitigation metrics compared to single pellet injection in DIII-D • Multiple shattered pellets injected for the first time as planned for ITER • Effect of multiple pellets appears to not sum directly in DIII-D plasmas expected measured • Extrapolation of single-SPI results to ITER may need to account for such effects
