tcv.diag.dmpx module

XTOMO diagnostics data

Written by Nicola Vianello

class tcv.diag.dmpx.Top

Bases: object

Class to load and analyze the data contained in the top chamber of DMPX. All the methods described as classmethod and so they can be called directly .. method:: read

Read the data calibrated in the same way as mpxdata matlab routine. It can read also single chords, accordingly to the call to Top

gains()

Return the gains used for the calibration of the chors

geo()

return the geometrical position of the chords

spectrogram()

It create and eventually plot the spectrograms(s)

static calibration_data(name)

static channels(shot, los=None)

Parameters:as fromshot. (Same) – Returns:

• String array containing the channels, already sorted out according to
• shot number

static fromshot(shot, los=None)

Return the calibrated DMPX signals.

Parameters:

• shot (int or MDSConnection) – Shot number or connection instance
• camera (int) – Number of the XTOMO camera
• los (int or sequence of ints) – Optional argument with lines of sight (LoS) of the chosen camera. If None, it loads all the 20 channels

Returns:

• An xarray.DataArray containing the data, time basis and all the
• information in dictionary

Examples

>>> from tcv.diag.dmpx import Top
>>> data = Top.fromshot(50730, los=32)

static gains(shot, los=None)

Provide the proper calibration factor for the signals so that can obtain directly the calibration used call:

Calibration, Gain = Top.gains()

static geo(shot)

Parameters:Input – shot: shot number Returns: Return type:The radial and vertical coordinates of the LoS

Examples

In [1]: from tcv.diag.dmpx import Top In [2]: x, y = Top.geo(50766)
