Overview of the JET ITER-like wall divertor

• Surface analysis of the JET ITER-like wall divertor is presented for 2013–2014.• Upper inner divertor remains the region of highest deposition and fuel retention.• Deposition at the divertor corners is influenced by strike point location.• Lifetime and erosion of tungsten coatings on JET divertor...

Description
Summary:• Surface analysis of the JET ITER-like wall divertor is presented for 2013–2014.• Upper inner divertor remains the region of highest deposition and fuel retention.• Deposition at the divertor corners is influenced by strike point location.• Lifetime and erosion of tungsten coatings on JET divertor tiles are discussed.• Dust and particulate generation in the divertor remains low,
