This submodule has scripts intended to aid in planning experiments which will use radiated power control. This covers both PCS code development and just choosing PCS settings to support experiments with prad control.
This module is used to:
Test smoothing timescales and calculations for the conversion from raw bolometer voltages to detected power on individual channels (the BOL_L01_V –> BOL_L01_P calculation).
Test and explore the conversion from individual power detected to inferred power emitted from a corresponding volume of plasma (e.g. BOL_L01_P vs. how much power was radiated in the slice of plasma seen by the channel’s view chord, taking into account toroidal extension of the emission zone, etc.)
Test and explore construction of physics quantities prad_tot, prad_core, prad_divl, and prad_divu using combinations of inferred power emitted from various sets of channels. This involves choosing which channels to sum and possibly assigning different weights.
Test specific PCS settings for forming prad estimates vs. standard signals (prad_tot, etc.).
Evaluate performance of radiated power control after using it in an experiment.
Analyze experiments with radiated power control.
