UCBNE Researchers and the search for Dark Matter

UCBNE Researchers and the search for Dark Matter

February 12, 2021


UCBNE Professor Karl van Bibber and his group of researchers were featured on campus news for their recent publication in Nature introducing a new experiment to harness the "weirdness of quantum mechanics to accelerate the search for the axion, one of two leading hypothetical subatomic particles that may make up the bulk of dark matter in the universe."

This new technique, called quantum squeezing, allowed the HAYSTAC detector to search for axions at twice the speed as before. “The HAYSTAC detector was already essentially at the quantum limit, and now we’ve actually found a way of circumventing the quantum limit entirely,” said co-author Karl van Bibber, executive associate dean at Berkeley’s College of Engineering and one of the senior researchers on the HAYSTAC project. “Several theoretical works are now predicting that the axion mass is right in the frequency range where HAYSTAC is ready to go next. And we’ve got the cavities and amplifiers all lined up and ready to search.”

Berkeley Team take first-ever measurements of Einsteinium

Berkeley Team take first-ever measurements of Einsteinium

February 5th, 2021

Researchers in Rebecca Abergel's lab obtained a small sample of einsteinium, a highly radioactive and difficult-to-obtain element, and made the first ever measurement of its bond distance. The study was published in Nature.

“Structural and Spectroscopic Characterization of an Einsteinium Complex,” has been published in Nature; A study co-led by Berkeley Lab scientist and UC Berkeley Nuclear Engineering (UCBNE) Assistant Professor Rebecca Abergel, Los Alamos National Laboratory (LLNL) scientist Stosh Kozimor, and a team of scientists: study co-authors Korey Carter, Katherine Shield (current UCBNE Grad student), Kurt Smith, Leticia Arnedo-Sanchez, Tracy Mattox, Liane Moreau, and Corwin Booth of Berkeley Lab; Zachary Jones and Stosh Kozimor of Los Alamos National Laboratory; and Jennifer Wacker and Karah Knope of Georgetown University—several of whom are graduate students and postdoctoral fellows.

The research was supported by the DOE Office of Science. Luminescence spectroscopy experiments were conducted at the Molecular Foundry at Berkeley Lab, and X-ray absorption spectroscopy at the Stanford Synchrotron Radiation Lightsource (SSRL) at SLAC National Accelerator Laboratory. With experimental facilities not available in 1952, when Einsteinium was discovered, the team measured the first-ever Einsteinium bond distance and with less than 250 nanograms of the element!

“There’s not much known about einsteinium,” said Abergel, who leads Berkeley Lab’s Heavy Element Chemistry group. “It’s a remarkable achievement that we were able to work with this small amount of material and do inorganic chemistry. It’s significant because the more we understand about its chemical behavior, the more we can apply this understanding for the development of new materials or new technologies, not necessarily just with einsteinium, but with the rest of the actinides too. And we can establish trends in the periodic table.”

The Nuclear Science and Security Consortium wins 5-year NNSA Grant for the third time

The Nuclear Science and Security Consortium wins 5-year NNSA Grant for the third time

January 27, 2021

Bay Area Neutron Group at Lawrence Berkeley National Laboratory on 08/22/2017 in Berkeley, Calif.

The Berkeley-based center, the NSSC, has won the National Nuclear Security Administration's (NSSA) 5-year, $25 million grant for the third time in a row. The NNSA first awarded the NSSC with a $25 million grant in 2011, then in 2016, and now for Sept. 2021. UC Berkeley's Nuclear Engineering Department Chair, Professor Peter Hosemann, highlights  this "is particularly notable given that most centers only receive it once or twice."

There is a recompetition for the grant every 5 years, as detailed by UCB Nuclear Engineering professor and NSSC program director, Jasmina Vujic: “We have to recompete — this is not renewal — every single time, meaning we have to write an entirely new proposal, have an entirely new team, and compete on a national level against anybody else."

The NSSC has supported over 550 undergraduates, graduates, postdoctoral students, faculty and specialists throughout its history. Focusing most of its funding to student support. “The consortium provides a strong draw for students into nuclear security and nonproliferation research areas,” said NSSC executive director and UCB researcher Bethany Goldblum in an email. “These scholars will go on to be leaders in nuclear nonproliferation, nuclear arms control, nuclear incident response, nuclear energy, and other nuclear-related fields.” 

We congratulate Professor Vujic, Dr. Goldblum, and those that contributed to the successful proposal. To another successful and fruitful 5 years ahead!

THE FUTURE OF NUCLEAR ENERGY: Interview with Peter Hosemann

The Future of Nuclear Energy: Interview with Peter Hosemann


If you get cancer treatment today, it’s very likely you will get injected with a radioactive substance. That technology is born out of the nuclear enterprise. Without reactors, you wouldn’t have it. There are numerous examples of the benefits of nuclear engineering beyond just nuclear power.
Dr. Peter Hosemann, Professor in the Department of Nuclear Engineering at University of California, Berkeley

In 2000, nuclear energy from just 30 countries provided approximately 15 percent of worldwide electricity capacity. But by 2019, its share had fallen to 10 percent, with the International Energy Agency (IEA) predicting that without intervention it would fall even further, to 5 percent, by 2040. That represents a significant drop in what could be an important source of clean energy.

“A nuclear power plant doesn’t take up a lot of space, and it can create a tremendous amount of energy, with a carbon footprint that is extremely low,” says Dr. Peter Hosemann, a professor in the Department of Nuclear Engineering at University of California Berkeley, where he is also the current chair.

Nuclear energy is the second-largest low-carbon power source in the world, second only to hydropower. According to the IEA, low-carbon electricity generation has to increase to 85 percent of the world’s energy, from its 36 percent share today, in order to stave off the most calamitous effects of climate change. Of major low-carbon energy sources, nuclear power is the least dependent upon geography.

“I believe the use of nuclear energy will increase as we become more serious about climate change and carbon emission,” Dr. Hosemann says. “I don’t think we have much of a choice.”

Dr. Peter Hosemann is a professor in the Department of Nuclear Engineering at the University of California Berkeley, where he is also the department chair. He received his MS and PhD degrees in material science from Montanuniversität Leoben, Austria.

Prior to joining the Department of Nuclear Engineering at UC Berkeley, Dr. Hosemann was a graduate research assistant and a post-doc at Los Alamos National Laboratory. His research features experimental material science for nuclear applications, with a focus on the structural materials used for nuclear components.

DOE- Sponsored Research Addressing Protective Equipment During The Pandemic UCB-NE/LBNL Collaboration

DOE- Sponsored Research Addressing Protective Equipment During The Pandemic UCB-NE/LBNL Collaboration

August 19, 2020

Screen Shot 2020-08-19 at 10.17.16 AM

Since March 2020 it became obvious that Personnel Protective Equipment (PPE) is essential to maintain core functions during a pandemic.

Essential workers are in need to receive reliable and convenient PPE, especially masks that are easy to breathe in. To address a need we work on a DOE-sponsored project with the Lawrence Berkeley National Laboratory (LBNL).

Our research and development focuses on two different aspects:

  1. Enhanced filtration and breathability by electrically enhanced filtration
  2. Castable mask designs (factory on a pallet)

The UCB-NE team of researchers Jason Duckering, Jeff Bickel, and Peter Hosemann worked together with Lawrence Berkeley National Laboratory scientists Deepti Tanjore, Jeffrey Urban, Jaeyoo Choi, and Chaochao Dun to provide rapidly available masks with conventional or enhance filtration to essential workers.
