# PYTOMO¶

Contacts: Tomas Odstrcil

## Short Description¶

Code for 2D tomographic inversion of SXR and bolometric data

## Keywords¶

SXR, bolometers, impurities, MHD modes, tomography

## Long Description¶

pyTomo is an advanced code for tomographical inversion from various line integrated diagnostics like SXR or bolometers. The main advantages are a simple GUI, very fast inversion and a high accuracy (depends on the quality of the input data). Details can be found on the DIII-D software page https://diii-d.gat.com/diii-d/PyTomo

## Typical workflows¶

This module is used for: * Inversion of radiation data * Investigation of 1D and 2D radiation profiles, poloidal asymmetries, and sawteeth * Determination of poloidal mode number. Further it can be used to estimate the impurity content and position of the magnetic axis.

## Supported devices¶

This OMFIT GUI works now only for the DIII-D tokamak, but pytomo itself supports several machines - DIII-D, AUG, TCV, JET, COMPASS, GOLEM, TORESUPRA. But not all modules for these machines for are still actively maintained.
