We performed an in situ
of the relative responsivity function of the Long-Wavelength Extreme Ultraviolet
(LoWEUS), while operating on the Lithium
Experiment (LTX) at Princeton Plasma Physics Laboratory. The calibration was
accomplished by measuring oxygen lines, which are typically present in LTX
plasmas. The measured
intensities of each oxygen charge state were then compared to the calculated emission
strengths given in the CHIANTI atomic database. Normalizing the strongest line in each
charge state to the CHIANTI predictions, we obtained the differences between the
and predicted values for the relative strengths of the other lines of a given charge
state. We find that a 3rd degree polynomial function provides a good fit to the data
points. Our measurements show that the responsivity between about 120 and 300
Å varies by factor of ∼30.
