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.

In this paper, operational methods of carbon sheet pump (CSP) which aims at control of hydrogen recycling are investigated. Although the pumping effect of CSP is confirmed in an actual plasma device, the experimental results suggest that a certain amount of gases are adsorbed on CSP under an actual plasma circumstance. The operational methods are contrived and are carried out for the reduction of the adsorbed gases on CSP. Time evolution of total pressures in several regions of the GAMMA 10 vacuum vessel is estimated by numerical analysis in order to evaluate the feasibility of applying CSP to the GAMMA 10 central region. These results suggest that CSP is applicable to actual plasma devices under a suitable operational method.
