Analysis of separatrix plasma parameters using local and multi-machine databases

PDF Version Also Available for Download.

Description

The ITER divertor modeling and database expert groups have assembled a scalar database of the edge plasma parameters for existing diverted tokamak devices as a means of enabling scaling studies of the SOL plasma. Data exist from ASDEX, ASDEX-Upgrade, C-MOD, COMPASS-D, DIII-D, JET, JFT-2M, and JT-6OU. We describe the scaling of plasma parameters at the outer midplane obtained from examination of this multi-machine database in this paper. The plasma parameters at the outer rnidplane are used as a boundary condition for all simulations of the SOL plasma, and hence understanding of the expected value of these parameters is crucial for ... continued below
