National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Determination of ECCD Current Profiles in DIII-D Discharges Using a Local Representation Methods.

DE2004825640

Publication Date	2001
Personal Author	Lao, L. L.; deGrassie, J. S.; Lin-Liu, Y. R.; Luce, T. C.; Chan, V. S.; Petty, C. C.
Page Count	12
Abstract	OAK-B135 A local representation is used to determine localized features in the current profiles due to ECCD in the DIII-D tokamak discharges from equilibrium reconstruction based on spectroscopic and external magnetic measurements. Initial results indicate that reconstruction using a local basis function can resolve very peaked ECCD profiles. The reconstructed narrow ECCD profiles are consistent with the quasi-linear Fokker-Planck results from the CQL3D code.
