Abstract
Experimental results of high Ip H-mode plasma, high triangularity plasma and radiative divertor are presented from the experimental campaign in 1995. H-mode operation was extended to Ip=4.5 MA. The highest level of stored energy of W~8 MJ was obtained with Ip=3.5-4 MA. The initial experiment of high triangularity plasma was carried out with IpN limit was increased by 30% and the highest record value of beta T=2.7% was obtained. With PNB=23 MW and alternate Neon and D2 puffing, 50% of the input power was radiated while the good core plasma performance was maintained in Ip=1.2 MA and BT=2 T, ELMy H-mode plasma.Keywords
