_Detachment_Indicator

Contacts: Cameron Samuell

Short Description

Methods for analysing detachment, predominantly during density scans

Keywords

Boundary, detachment, SOL

Long Description

This module analyses an evolving shot to provide indicators on whether or not detachment has occured. For instance, examining Te, JSAT, heat flux etc evolving during a density or impurity puff scan.

Typical workflows

This module is used to:

• Overview a number of boundary diagnsotics as a function of time.

• Remap to arbitrary x-domain (eg. greenwald fraction, degree of detachment (DOD), or strike point position).

• Analyze the onset of detachment (between ELMs) as a function of density from the point of view of multiple independent diagnostics.

• Calculate DOD for a given langmuir probe.

• Compare discrete time periods (eg. before & after JSAT roll-over)
