Proving DRACO will deliver
The United States is now closer than it has been in over five decades to launching the first nuclear thermal rocket into space, thanks to DRACO—the Demonstration Rocket for Agile Cislunar Orbit.

Five line integrated spectra are obtained from Hanbit mirror plasma using optical chords installed in the horizontal direction of central cell chamber.
In this work, we describe the spectroscopic method to obtain the local spectra in the radial direction by applying the deconvolution method to the five line integrated spectra. Among several fitting methods, the deconvolution fitting is well known as the most effective one.[1]
From these, the local intensity profiles and ion temperature are obtained. In order to compensate for the instrumental broadening of spectrometer, a slit function obtained from the low pressure mercury line 253.65 nm is used. The C III 229.68 nm line from the Hanbit central cell plasma is selected as sample data. We applied the deconvolution fitting method using a slit function to eliminate the instrumental broadening.
