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 technology of the free electron maser (FEM) has advanced to where it now is an attractive source for electron cyclotron heating (ECH) in tokamaks at reasonable cost. FEM's are capable of producing CW power at frequencies 50–400 GHz with power levels up to 5 MW/module. They can operate as a high gain (30–40 db), wide band amplifier (Δf/f = 5–10%). Such systems incorporate high quality (low emittance and energy spread) electron beams of moderate current which are electrostatically accelerated before passing through a large amplitude wiggler. Highly efficient recovery of the energy from the “spent” beam is feasible and enhances the total FEM system energy to nearly 50% even though the beam extraction efficiency is rather modest.
