Workflows
The IMP12 project has provided a series of prebuilt
Kepler workflows around
equilibrium reconstruction, linear MHD stability, non-linear MHD, and
disruptions.
Below the prototype workflows are described as they are stored in the
keplerworkflows repository under
Gforge . Most prototypes come with
several production versions which are also stored in the
keplerworkflows repository.
The list is constantly expanding.
IMP12's workflows are hosted in the following categories:
- fixed_boundary_equilibrium - free_boundary_equilibrium - linear_MHD

Free Boundary Equilibrium Reconstruction
EQUAL slice
The workflow equalslice.xml reads JET magnetics data from the ITM database and runs the EQUAL free boundary equilibrium reconstruction code to calculate the equilibrium. A Python actor is included to visualize the resulting separatrix curve (see figure below).

High Resolution Fixed Boundary Equilibrium Reconstruction
HELENA
The workflow helena_aug.xml reads an equilibrium CPO from the ITM database (which may contain as little as the input profiles and boundary curve) and calculates the high resolution fixed boundary equilibrium inside the specified boundary curve using the HELENA actor. A Python actor is included to visualize the resulting equilibrium.
| Type | Actors | Input CPOs | Output CPOs |
|---|---|---|---|
| linear | ualinit
helena ualpyactor ualcollector |

EQUAL-HELENA
The workflow equal_helena.xml reads JET magnetics data from the ITM database and runs the EQUAL free boundary equilibrium reconstruction code to calculate the equilibrium. The resulting equilibrium is then reconstructed within the separatrix with the high resolution equilibrium solver HELENA. A Python actor is included to visualize the pressure and current density profiles along with the safety factor q and a two-dimensional plot of the flux surfaces (see figure). The path parameter is optional and can be used to redirect verbose output to the specified directory.

PROGEN-HELENA
Two prototype workflows fall in this category: progen_helena_analytic.xml and
progen_helena_aug.xml.
The first of these generates an equilibrium from an analytic definition of the profiles and
the shape. The second reads experimental profiles and generates an experimental equilibrium
for ASDEX Upgrade.
Analytic equilibrium
The workflow progen_helena_analytic.xml uses the simple tool PROGEN to generate analytic profiles for p', FF' and the plasma boundary which are fed to the high resolution fixed boundary equilibrium solver HELENA. One Python actor shows the incoming p' and FF' profiles while a second Python actor shows the resulting equilibrium (see figures). The path parameter is optional but can be used to read profiles from file and to redirect verbose output to the specified directory.
| Type | Actors | Input CPOs | Output CPOs |
|---|---|---|---|

Experimental equilibrium
The workflow progen_helena_aug.xml uses the simple tool PROGEN to read the profiles for p', FF' and the plasma boundary from files. These are then fed to the high resolution fixed boundary equilibrium solver HELENA. One Python actor shows the incoming p' and FF' profiles while a second Python actor shows the resulting equilibrium (see figures). The path parameter is used to read the profiles from file and to redirect verbose output to the specified directory.
| Type | Actors | Input CPOs | Output CPOs |
|---|---|---|---|
| linear | ualinit
progen helena ualpyactor ualcollector |
none | equilibrium |
JALPHA-HELENA
The workflow jalpha_helena_analytic.xml reads a precalculated equilibrium
(for instance calculated with HELENA) from the data base, modifies the
pressure and current density profiles with the module JALPHA and calculates
the new equilibrium using the HELENA actor.
The intention here is to modify an experimental equilibrium for edge
stability analysis, so called j-
diagrams.
A Python actor shows the pressure and current density profiles of the
original equilibrium another the modified profiles while a third Python actor
shows the new equilibrium (see figures).
The path parameter is optional and
can be used to redirect verbose output to the
specified directory.

Linear MHD Stability Analysis
ILSA
The workflow ilsa_aug.xml reads an equilibrium CPO from the ITM database containing a high resolution fixed boundary equilibrium. It then analyzes the equilibrium for linear MHD stability and calculates a spectrum of growthrates and frequencies vs. toroidal mode numbers using the linear MHD stability actor ILSA. A Python actor is included to visualize the resulting spectrum (see figure below).

EQUAL-HELENA-ILSA
The workflow equal_helena_ilsa.xml reads JET magnetics data from the ITM database and runs the EQUAL free boundary equilibrium reconstruction code to calculate the equilibrium. The resulting equilibrium is then reconstructed within the separatrix with the high resolution equilibrium solver HELENA. Using this high resolution fixed boundary equilibrium, the linear MHD stability module ILSA determines the stability of the equilibrium. A Python actor is included to visualize the pressure and current density profiles along with the safety factor q and a two-dimensional plot of the flux surfaces. The path parameter is optional and can be used to redirect verbose output to the specified directory. The resulting MHD CPO is stored in the database using the ualcollector actor.

for ASDEX Upgrade. Both workflows then analyze the linear MHD stability of the resulting
equilibria.
