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.

Data from single chord Doppler ion temperature measurements in spheromaks have been analyzed with the aid of a one dimensional equilibrium charge state transport code. With electron temperature profiles known from Thomson scattering and estimates for transport rates, we can determine the radial location for the impurity line emission. The results of these analyses are the reconstruction of one dimensional ion temperature profiles. From this Ti profile data we can now correctly calculate volume averaged confinement quantities. Our initial findings are that previously quoted values of 〈β〉 and 〈τE〉 were underestimated by a factor of ∼ 4 and now the highest quoted energy confinement times are ∼ 50µs.
