Perpetual Atomics, QSA Global produce Am fuel for nuclear space power
U.K.-based Perpetual Atomics and U.S.-based QSA Global claim to have achieved a major step forward in processing americium dioxide to fuel radioisotope power systems used in space missions. Using an industrially scalable process, the companies said they have turned americium into stable, large-scale ceramic pellets that can be directly integrated into sealed sources for radioisotope power systems, including radioisotope heater units (RHUs) and radioisotope thermoelectric generators (RTGs).

The geometrical efficiency equation for a proton recoil telescope exposed to a monoenergetic point neutron source is solved by a power series expansion that permits simple and accurate reduction of raw telescope data to absolute neutron fluxes or source strengths. Two parameters are allotted for description of source anisotropy and three parameters are allotted for description of hydrogen scattering anisotropy in the center-of-mass system. The relativistic transformation of the hydrogen differential scattering cross section from center-of-mass to laboratory system is used.
