Get the RF Data

This section lets you set the ICRF parameters. It reads the RF power for each antenna if the power waveforms exist.

\* Options are:                    Antenna1      Antenna2
 1) Power             [ZERO    ] < 0.000E+00> < 0.000E+00> W
 2) % Error                      <       0.0> <       0.0>
 3) Frequency                    < 47.00E+06> < 47.00E+06> Hz
 4) Width                        < 0.100    > < 0.100    > m
 5) Dwall                        < 3.000E-02> < 3.000E-02> m
 6) PA Poloidal angular extent   <  1.00    > <  1.00    > radians
 7) TP Toroidal phase difference <  3.14    > <  3.14    > radians
 8) PP Poloidal phase difference < 0.000E+00> < 0.000E+00> radians
 9) TK Toroidal k spectrum width < 0.000E+00> increment  <  7.00    > (1/m)

10) AT Archive the toroidal magnetic field in 2D .............. <YES>
11) AD Archive the divergence of the rf Poynting flux in 2D ... <YES>
12) AV Archive the velocity distribution in 2D ................ <YES>

13) NP Average the heating profile with no spreading .......... <YES>   Or
14) BO Average the heating profile over a banana orbit ........ <NO>

15) Include ICRF .............................................. <NO>

• Power: (no standard; values read from waveforms)
• Frequency: hand-entered RF frequency, typically Hz.
• Width: 0.1 m for both antennae.
• Dwall: 0.03 m for both antennae.
• Poloidal angular extent: 1.00 radians. The width, Dwall and poloidal angular extent characterize the antenna geometry and should remain fixed as long as the antenna hardware itself remains unaltered.
• Toroidal phase difference: 3.14 radians (out-of-phase) is the standard operating mode. Enter 0. if the antenna was operated in-phase.
• Spectrum width: 0.0
• Spectrum increment: 7.0 m^-1. The spectrum width and increment control the k_z's which will be included in the spectrum calculation. If you want to perform an analysis including several k_z's, set the spectrum width equal to the maximum in the spectrum. The increment represents the spacing between 's included in the spectrum; the code will model a spectrum of for j = 1,2,3, ... up to a maximum
• All of the archive flags should be set to yes.
