## Phi (0,0) time slices for base case and -30% case

Sept 15, 1997

Below is a link to radial profiles of the flux surface averaged potential
(the phi(0,0) mode) at six times for my base case run.
This is (e Phi / T_i) (L_ne / rho_i), so my curves should
be divided by eta_i=3.11 to compare to Andris's curves, which
are (e Phi / T_i) (L_T / rho_i)
(Andris's PDF file is here).
Eyeballing it very roughly, the levels look comparable to Andris's,
but time averaged spectra are needed for a quantitative
comparison.

Phi00 plots vs. minor radius for base case from
gyrofluid run

The six time slices are at: 345, 600, 840, 1067, 1294, and 1515 L_T/v_ti.
The time history of chi_i for this run is the first plot on
this page.

Next are radial profiles of the flux surface averaged potential
at four times for my -30% case run. Now these curves
should be divided by eta_i=2.16 to compare to Andris's
(Andris's PDF file is here).
(I used R/L_T = 4.8 for this run.)
This case looks significantly different from Andris's--
the gyrofluid phi(0,0) is not stationary late in the run.

Phi00 plots vs. minor radius for -30% case from
gyrofluid run

The four time slices are at: 333, 624, 892, and 1169 L_T/v_ti.
The time history of chi_i for this run is the blue curve
here.
