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 marginal stability of MHD modes is discussed in application for high beta multiple mirror experiments planned at Budker Institute of Nuclear Physics. Flute modes arc dangerous in axisymmetric systems with β < 1. In the case of “wall confined” plasmas, (β ≫ 1), pressure slightly varies along the radius providing less radial gradient and more stability against MHD modes. Effect of ion-ion viscosity becomes important in corrugated magnetic field. It results in the reduction of the growth rate by a factor β1/2. In the process of start up and plasma heating β < 1. If flute modes are stabilized during this period by the line-tying mechanizm ballooning modes are still unstable when β > βcr. A very low ballooning margin is predicted in multiple mirror with the large number of cells: βcr < π2 /N2. For the number of cells N ≃ 10: βcr ≃ 5%. Results of the calculations are discussed in the context of old and new multiple mirror experiments.
