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.

Refueling by hydrogen ice pellet injection has been studied in various plasmas. The research of pellet ablation related to refueling is very important object. In the central-cell plasma of tandem mirror GAMMA 10, we measured the position of pellet ablation by vertical and horizontal arrays of H detectors and a high-speed CMOS camera. We found that the penetration depths with applying electron cyclotron heating (ECH) is shorter than that without ECH. It suggests that the pellet ablation is strongly affected by warm electrons produced with ECH. Moreover, we investigated the effects of neutral beam injection (NBI) to the pellet ablation, which showed the pellet ablation in the situation of higher density plasma. The pellets penetrate through the plasma without applying ECH or NBI. We observed the pellet ablation at each position by using vertical and horizontal arrays of H detectors and a high-speed CMOS camera with the interference filter.
