To address the risk that, in a fusion reactor, conventional single-null divertor (SND) configuration may not be able to handle power exhaust, alternative configurations, such as Snowflake (SFD), are investigated TCV. The expected benefits of SFD-minus terms load and peak heat flux discussed compared experimental measurements. In addition, key results obtained during last years summarized.
