The high T_i mode plasma is characterized by a high central ion temperature, T_i(0), and is associated with a peaked electron density profile produced by neutral beam fueling with low wall recycling. Transition from L mode to high T_i mode has been studied in CHS. The central ion temperature in the high T_i mode discharges reaches to 1 keV which is 2.5 times higher than that in the L mode discharges. The ion thermal diffusivity is significantly reduced by a factor of more than 2 - 3 in the high T_i mode plasma. The ion loss cone is observed in neutral particle flux in the energy range of 1 - 6 keV with a narrow range of pitch angle (90 pm 10 degree) in the high T_i mode. However, the degradation of ion energy confinement due to thls loss cone is negligible.", "subitem_description_type": "Abstract"}]}, "item_5_source_id_10": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "0915-633X", "subitem_source_identifier_type": "ISSN"}]}, "item_5_text_25": {"attribute_name": "登録情報", "attribute_value_mlt": [{"subitem_text_value": "Made available in DSpace on 2010-02-05T10:19:47Z (GMT).
