Description
First β scan experiments have been made in ASDEX Upgrade in H-mode plasmas with type-I ELMs. Two sets of discharges, performed in different density ranges, scan β between βN = (1.4-2.2) and βN (1.4-2). Global analysis of these dedicated experiments exhibits a strong unfavourable β scaling as Bτth ∼ β-0.9. This tendency is confirmed by a local analysis which shows an increase in the thermal heat diffusivity with increasing β as χeff/B ∼ β0.65. These results are discussed and compared with studies made in DIII-D, JET and JT-60U
