摘要: Divertor plasmas with strong external gas puffing in ASDEX Upgrade have shown very efficient impurity retention, increasing the divertor neutral density. The experiments presented here use feedback-controlled puffs discharges different pumping speed to keep flux density same. This allows for first time a decoupling of and flow. resulting are almost identical show clearly demonstrating importance over externally induced {copyright} {ital 1996 American Physical Society.}
