Short Description

Mirror and open magnetic system variants of the tokamak codes are under development. CQL3D-M ("M" for mirror), MCGO-M, and GENRAY-C ("C" for Cartesian) have been converted, at least in part, from their eponymous codes. Fully nonlinear bounce-averaged collisional Fokker-Planck solutions are obtained for f(vpar,vperp,rho;t) on transport time scales. Variation of f along the magnetic field is obtained using COMs, giving a 2-space,2-velocity solution. These codes will be further developed, and the others will be converted from the tokamak versions as needed/funded.

Date/Active Use

2011

Authors

Yu.V. Petrov, R.W. Harvey

Language

F77/F90 + MPI

Purpose/Function/Special Features

The purpose is for applications to open magnetic systems such as the Proto-MPEX [6,7], C-2U [8,9], and GDT[10,11].

Basic Algorithms

Equilibrium geometry is specified by analytical formulas and by the eqdsk format files. For CQL3D-M, a parallel electric field maintaining charge balance is determined interatively at each time step.

Coupled Diagnostics

The CQL3D suite of diagnostics are available.

Key Results

Please see Refs. 7 and 9, below, for first results from GENRAY-C, and Ref. 11 for first results from CQL3D-M. More recent work has focussed on University and Wisconsin, Madison devices [4,3] and advancements [1,2].

A major new application of CQL3D-M is to use the obtained distributions as an intial condition in a PIC code, leading to growth and quasi-saturation of gyrokinetic instabilities in the PIC code. This couples the transport time-scale CQL3D-M code to the micro-instability growth times in VPIC[12].
