摘要：

Results are presented from studies of the formation of current sheets during exciting a current aligned with the X line of the 3D magnetic configuration, in the CS-3D device. Enhancement of the guide field (parallel to the X line) was directly observed for the first time, on the basis of magnetic measurements. After the current sheet formation, the guide field inside the sheet exceeds its initial Value, as well as the field outside. it is convincingly demonstrated that an enhancement of the guide field is due to its transportation by plasma flows on the early stage of the sheet formation. The in-plane plasma Currents, which produce the excess guide field, are comparable to the total current along the X line that initiates the sheet itself. (C) 2009 Elsevier B.V. All rights reserved.
