Russia withdraws from 25-year-old weapons-grade plutonium agreement
Russia’s lower house of Parliament, the State Duma, approved a measure to withdraw from a 25-year-old agreement with the United States to cut back on the leftover plutonium from Cold War–era nuclear weapons.

We explore the utility of using a gas other than hydrogen isotopes to neutralize energetic beams of D+ or H+ for applications in magnetic confinement fusion. We find that, at D+ energies above 160 keV, helium, relative to hydrogen, offers significant improvements in neutralization efficiency and in enrichment of the full energy component of the beam, and that similar advantages accrue with neon at D+ energies in excess of 200 keV.
