&GAS: OPTIONS


GAS-PRINT

This option is responsible for making a printout of all available information on the gas.

The tables are printed when the gas section is being left, not when the option is switched on. Use e.g. &MAIN to close the section. As a consequence, if you wish to output the tables to a file, then you have to start the rerouting just before leaving the section and revert to normal output once you are in the next section:

&GAS
magboltz argon 80 co2 20
opt gas-print
> Ar_80_CO2_20.print
&MAIN
>

The output can not be used directly as input to the program, use the WRITE instruction for that purpose.

[This option is off initially, its setting is remembered from one gas section to the next.]


GAS-PLOT

Switching on this option requests plots of the drift velocity, the ion mobility, the diffusion coefficients, the Lorentz angle, the Townsend coefficient, the attachment coefficient and the ion dissociation coefficient to be produced.

These plots are made when the gas section is left, not when the option is switched on. Use e.g. &MAIN to close the section.

The representations used in the graphs are the following:

With the PLOT-OPTIONS command, you have further control over the axes (linear or logarithmic) and the vertical scale of these plots. This command also enables you to suppress one or more of the plots.

Use the ATTACHMENT, DRIFT_VELOCITY, GET_E/P_TABLE, ION_MOBILITY, LONGITUDINAL_DIFFUSION, LORENTZ_ANGLE, TOWNSEND, TRANSVERSE_DIFFUSION, VELOCITY_E, VELOCITY_BTRANSVERSE and VELOCITY_ExB procedures for fully customised plots.
