GUI for TRANSP input collection
Execute trgui. If an error occurs, make sure you have /afs/ipp/aug/ads/@sys/diags/ in your $PATH.
The command opens this GUI:
You need to fetch
1d: Ipl, Bt, Uloop, Zeff, Heating
and finally to write a Namelist.
Clicking the Separatrix button the following window pops up:
Click File -> Read and fit separatrix and the equilibrium data + fit
You can navigate through the data in time with the time bar (bottom of
the figure) or the play/pause, forward and rewind buttons (below the figure)
If you are satisfied, click File -> Store u-file
Clicking the Profiles button the following window pops up:
Choose the profiles type ('ne', 'Ti', 'Te'...) and for each of
them the diagnostics you want to use, unrolling the menu (click with the mouse'
left button). In most cases, IDA
is preferable when available.
If you choose 1D fit, i.e. a recursive cubic spline at each time
frame, click Fit profile and you get to the
If you choose 2D fit, make sure to click Load profiles
first. This method:
allows to combine several diagnostics of the same plasma profile (e.g. core +
edge CX), also with different time bases
uses experimental error bars (instead of a uniform value set by the user)
as fit constraints
is based on time-space smoothing based on the inversion of the diffusion
equation, so it delivers smooth gradients
some care is needed in case of signal modulation in time: the time
dependence could be smoothed out
