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 and feasibility of neutral beams of A ≥ 6 amu formed from negative ions, and also of D0 formed from D−. The negative ions would be accelerated to ∼1 to 2 MeV/amu and neutralized, whereupon the neutral atoms would be used to heat and perhaps to drive current in magnetically confined plasmas. Such beams appear feasible and offer the promise of significant advantages relative to conventional neutral beams based on positive deuterium ions at ∼150 keV.
