The Plasma Microturbulence<br />

Project supports a 2x2 matrix<br />

<strong>of</strong> codes (geometry x algorithm),<br />

each type <strong>of</strong> code is tuned <strong>to</strong><br />

optimize in various regimes <strong>and</strong><br />

so are optimized <strong>to</strong> study certain<br />

types <strong>of</strong> problems.<br />

Codes using flux-tube geometry<br />

(shown here) take advantage <strong>of</strong><br />

short decorrelation lengths <strong>of</strong> the<br />

turbulence perpendicular <strong>to</strong> magnetic<br />

field lines. Multiple copies <strong>of</strong><br />

a flux-tube pasted <strong>to</strong>gether represent<br />

a <strong>to</strong>roidal annulus.
