PR: American Nuclear Society welcomes Senate confirmation of Ted Garrish as the DOE’s nuclear energy secretary
Washington, D.C. — The American Nuclear Society (ANS) applauds the U.S. Senate's confirmation of Theodore “Ted” Garrish as Assistant Secretary for Nuclear Energy at the U.S. Department of Energy (DOE).
“On behalf of over 11,000 professionals in the fields of nuclear science and technology, the American Nuclear Society congratulates Mr. Garrish on being confirmed by the Senate to once again lead the DOE Office of Nuclear Energy,” said ANS President H.M. "Hash" Hashemian.

Two kinds of tunable coherent photons for positronium formation and annihilation can be generated by coalescing focused, high-intensity e and e+ beams which are accelerated in the same direction. Positronium formation can be enhanced by laser irradiation or by installing an undulator magnetic field in cases where the density of e and e+ plasma is not high. In the case of very high density, slender rod-type geometry plasma, positronium can be formed by super-radiant, superfluorescence, or amplified, spontaneous emission processes, and a coherent laser can be generated.
