Tungsten (W) erosion and edge transport are investigated for EAST L-mode discharges with different gas injection. It is found that W erosion can be suppressed or mitigated by Ne or D2 seeding when divertor detachment is achieved. Compared to edge D2 fueling. Ne seeding from the divertor target is favorable for full detachment condition and thus W erosion suppression. https://danddcollectiblers.shop/product-category/noodlies/
