A larger quench propagation velocity is preferable in order to prevent local temperature from being increased significantly. In a multi-strand cable whose strands are individually insulated, it has been reported that the quench propagation velocity increases by a current redistribution between strands. However, influences of current redistribution on a quench velocity for a cable made of non-insulated strands have not been studied. We examined the relations between the current redistribution and the quench propagation velocity in a Rutherford cable made of non-insulated strands. Measurements were performed in the cables with three contact conditions between strands, and it was found that the quench propagatin velocity and the current redistributions depended on the contact conditions between strands. A measurement was also performed in the cable without polyimide tape for the cable insulation, and we found that the polyimide tape also influenced on the quench propagation velocity. A numerical simulation of current redistribution using a simple model was performed. We made comparisons between the test and the numerical results, and there was good agreement each other. We analyzed the numerical results in detail, and we found that the current redistribution occurred around the quench front caused the incerase of the quench propagation velocity.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_12_description_45":{"attribute_name":"学位授与年度","attribute_value_mlt":[{"subitem_description":"1999","subitem_description_type":"Other"}]},"item_12_description_5":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"Includes
