Nationwide brainstorm: Workshops focus on nuclear energy innovation
At the heart of the modern energy debate is a struggle between the need for more energy globally, while simultaneously achieving lower emissions. Nuclear energy is uniquely positioned to help respond to these dueling necessities, but innovative advancements must overcome considerable barriers. In general all sides of the polarizing topic agree that the nuclear energy sector could benefit from significant innovation.
DOE's Idaho National Laboratory recently organized more than 120 global energy experts in six cities across the U.S. to discuss innovation in nuclear energy. The goals: gather input from experts to help improve strategy for innovating nuclear technologies and start an ongoing dialogue among experts and laypersons alike. -
Lawrence Livermore deploys world’s highest peak-power laser diode arrays
DOE's Lawrence Livermore National Laboratory has installed and commissioned the highest peak power laser diode arrays in the world, representing total peak power of 3.2 megawatts (MW).
The diode arrays are a key component of the High-Repetition-Rate Advanced Petawatt Laser System (HAPLS), which is currently under construction at LLNL. When completed, the HAPLS laser system will be the world’s highest repetition-rate petawatt laser system and will be installed in the European Union’s Extreme Light Infrastructure Beamlines facility, under construction in the Czech Republic.

A tale of two colliders
Dennis Perepelitsa, a Brookhaven Lab physicist exploring the mysteries of nuclear physics at the Relativistic Heavy Ion Collider (RHIC) and the Large Hadron Collider (LHC), has the distinction of being the first person to earn outstanding Ph.D. thesis awards from both research communities. His Ph.D. work, based on complementary data collected at the PHENIX and ATLAS detectors at these two particle colliders, showcased intriguing findings that have upturned physicists’ understanding of something they thought they knew well—an ongoing mystery that is guiding part of the research programs at both machines now.
“I’ve been very lucky to work on these two world-class experiments with leaders in the field as my advisors,” Perepelitsa said. “When I started out working on PHENIX/RHIC, we observed some very strange features in the data, and went to the LHC to look for answers to the puzzling results. Now we’re taking what we learned at the LHC and reinvesting that knowledge back into this year’s RHIC run.”
