Division Spotlight
Fusion Energy
This division promotes the development and timely introduction of fusion energy as a sustainable energy source with favorable economic, environmental, and safety attributes. The division cooperates with other organizations on common issues of multidisciplinary fusion science and technology, conducts professional meetings, and disseminates technical information in support of these goals. Members focus on the assessment and resolution of critical developmental issues for practical fusion energy applications.

Former Exelon CEO Chris Crane remembered for “transformational milestones”
Crane
Exelon announced that Chris Crane, the company’s former chief executive, passed away on Saturday in Chicago at the age of 65.
Crane served as the company’s president and CEO from 2012 until his retirement in December 2022. During his tenure, he steered the energy company through several transformational milestones, including the successful mergers with Constellation Energy in 2012 and Pepco Holdings in 2016, creating the largest utility business by customer count in the United States.
In 2022, with the spin-off of Constellation as the generation and retail side of energy business (with the largest U.S. nuclear fleet), Crane led the creation of a stand-alone transmission and delivery energy company.

The current point design for ignition targets for the National Ignition Facility has a beryllium ablator. As Be is essentially impermeable to hydrogen, conceptually the shell will be filled by boring through the shell with a laser, then attaching a fill-tube. Examination of focused ion beam (FIB) technology is under way as an alternative to laser drilling. Holes of 40, 20, and 15 m diameter have been successfully ion milled through a 47 m thick Be layer. These holes are clean, though take several hours to make, and the geometry is limited by the aspect ratio of the depth to the diameter of the hole. Work was also done to investigate the possibility of using a FIB to create a counter-bore for the insertion and attachment of a fill-tube in a Be shell which has a pre-existing hole. Because the FIB can be controlled to sub-micron scales, the counter-bore can be easily centered on the through-hole and the side-walls and base of the counter-bore can be made very smooth. Finally, a proof-of-principle experiment was made to show that a Be wire could be attached to an in-situ micromanipulator and then be placed inside the counter-bore.
