摘要: Modification of the divertor to a W-shaped pumped and installation pumping has enabled demonstration 'puff pump' effect in injected neon, albeit speed was modest (∼14 m 3 /s). It demonstrated ELMy H-mode plasmas with P NB ≤ 25 MW that neon seeding useful control radiation profiles main plasmas, while large loss from MARFE sustained. suggested enrichment plasma, which enhanced by D 2 puff, effectively improved efficiency neon.
