在JFT-2 M托卡马克装置上，研究了折流板对偏滤器和刮削层等离子体的影响以及紧凑环注入加燃料的影响，得到了以下结果。偏滤器等离子体中的一种类似跃迁的现象，发生在平均主等离子体密度约为2-2.5× 1019 m −3时，与偏滤器板上的温度从9 eV突然下降到3 eV相一致。偏滤器内外板的负偏置对偏滤器功能有明显的改善，但这种改善只有在偏置在SOL中形成的E×B流方向是从内向外时才能观察到。在欧姆加热（OH）等离子体中，注入CT后放电中的粒子加燃料量可达3.4× 10 ~（18），且WMHD增大，PRAD和Vloop减小。
In the JFT-2M tokamak, the effects of baffle plates on the divertor and the scrape-off-layer (SOL) plasma and the fueling by the compact toroid (CT) injection have been investigated, and following results were obtained. A transition-like phenomenon in the divertor plasma, which occurs at the average main plasma density of about 2–2.5×1019m−3, was observed and coincides with the abrupt drop of the temperature on the divertor plate from 9 to 3 eV. The negative biasing of both inside and outside divertor plates showed a significant improvement of the buffled divertor function, which was only observed when the direction of the E×B flow formed by the biasing in the SOL is from the inside to the outside. The particle fueling up to 3.4×1018was observed and increase of the WMHDand decrease of PRADand Vloopwere observed in discharges with the CT injection in Ohmic heating (OH) plasmas.
