Founding Scientific Advisors

Before Xcimer was officially incorporated, a small group of physicists, scientists and engineers, including the inventors of the excimer laser, contributed their time and advice to help arrive at the compelling and practical power plant architecture we are now pursuing. We are grateful for their contributions.
