Validation of collisional radiative modelling of emission line ratios for helium beam plasma diagnostic

Collis, S; Dall, Robert; Howard, John; Andruczyk, D; James, Brian W

Description

A time-dependent collisional radiation model has been used to validate the use of a pulsed helium beam to measure electron temperature profiles in the H-1NF flexible heliac. The diagnostics technique is based on the measurement of helium spectral line ratios which are a strong function of electron temperature while being a weak function of electron density. The validation procedure involves comparing measured and calculated emissivities of spectral lines emitted by helium atoms as a function of...[Show more]
