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.

The feasibility of heating TJ-II plasmas by electron Bernstein waves (EBWs) is studied. As a first approach, the Clemmov-Mullaly-Allis diagram is studied to explore the possible heating regimes, and the TRUBA ray- and beam-tracing code, which has been adapted to the complicated TJ-II geometry, is used to perform detailed calculations. The final result is that it is possible to heat plasmas by overcoming the cutoff density of electromagnetic modes by injecting the O mode and X mode at the first harmonic, exploiting the O-X-B1 and the X-B1 schemes. Transport simulations are performed to estimate the plasma parameters that are expected in those regimes and to study the transition from the X mode at the second harmonic to EBW heating at the first harmonic.
