Abstract
The effectiveness of the pumped divertor during the 1994/95 experiment al campaign of the Joint European Torus (JET) [P.-H. Rebut, R. J. Bick erton, and B. E. Keen, Nucl. Fusion 25, 1011 (1985)] has allowed the p ursuit of a broad-based research program that is highly relevant to th e International Thermonuclear Experimental Reactor (ITER) [K. Tomabech i and the ITER Team, Nucl. Fusion 31, 1135 (1991)]. High-performance h ot-ion discharges with high confinement (H-modes) free of edge localiz ed modes (ELMs) have set a JET record neutron rate in deuterium, but a re limited by various magnetohydrodynamic (MHD) phenomena to beta N < 1.8, where beta(N)=beta/(I/aB), beta is the ratio of the plasma pressu re to the toroidal field pressure, I is the plasma current, B is the t oroidal field, and alpha is the horizontal minor radius of the plasma. Quasi-steady-state ELMy H-modes have also been studied at high power, high current, and high beta. The underlying energy transport exhibits a gyro-Bohm dependence that is lost close to the H-mode threshold and at high beta. ELMy H-modes with detached divertor plasmas and radiati ve power exhaust (the operating regime foreseen for ITER) reduce the p ower loading to the targets, but at the expense of main plasma confine ment and purity. Beryllium has been compared with carbon fiber composi te as a divertor target material and melting has been induced at ITER reference off-normal heat loads, but only a moderate degree of self-pr otection of the beryllium target was found.
