LBNL Participates in UF6 Cylinder Measurement Campaign at Fuel Fabrication Facility
Daniel Hellfeld, a Research Scientist in the Applied Nuclear Physics Program, traveled to the Pacific Northwest in April 2022 to participate in a week-long measurement campaign to collect gamma-ray spectra from Type-30B UF6 cylinders used to store and transport uranium of various enrichments for use in nuclear fuel assemblies (see Figure 1). During the week, 12 different cylinders with U-235 enrichments ranging from 0.2% (depleted) to 4.95% (low-enriched) were measured using a room-temperature operated, semiconductor-based, 3D position-sensitive pixelated CdZnTe (CZT) detector system available commercially from H3D Inc.

88-Inch Cyclotron Receives Funding for Upgrades
The 88-Inch Cyclotron facility provides high-intensity, medium-charge-state ions as well as low-intensity, high-charge-state ion beams to its users. The positively charged ion beams are used for experiments ranging from Super Heavy Element searches to radiation effects chip testing at the 88-Inch Cyclotron’s BASE Facility. This flexibility is especially important to the radiation effects testing community […]

Safety Note – Kudos from your DSC Last October, RNC successfully completed a safety day/office clean-out exercise in B70. Staff from the program reviewed their offices for earthquake strapping, electrical, and housekeeping issues. The work they did assured us that employees will have a safe place to work and significantly reduced the amount of excess […]

Inclusion, Diversity, Equity, and Accountability Moments
Best Practices for Hybrid Meetings As we enter a new phase in the pandemic when more and more people are able to safely work together at the lab, our use of fully remote meetings may be coming to a close. Now many of us find ourselves in the situation of holding meetings with in-person participants […]

LBNL Researchers guide “Detector One” Tracking Design at the EIC
The Electron Ion Collider (EIC) will be the next major facility in Nuclear Physics and LBNL’s Relativistic Nuclear Collisions (RNC) group is playing a leading role in its development. The EIC will be constructed at Brookhaven National Laboratory (BNL) and begin data taking in the 2030s, enabling detailed studies of protons, neutrons and atomic nuclei. […]

Illuminating two-photon exchange effects in e-p scattering
Electron scattering is a powerful tool for studying hadron and nuclear structure. In particular, one‑photon (OPE) and two‑photon exchange (TPE) mechanisms play an important role in the scattering of electrons on nuclei. The OPE mechanism is the dominant interaction, while the TPE is a small but sometimes critical contribution. In terms of the state of […]

Advanced sensor networks for radiological detection
A team from LBNL’s Applied Nuclear Physics program, in collaboration with scientists from Argonne National Laboratory, have been working to realize a city-scale multi-sensor testbed with which to explore new techniques in intelligent, networked sensing for radiological and nuclear detection. Figure 1 shows a prototype system installed at LBNL for evaluation. In June and July, […]

Heather Crawford leads the first FRIB experiment
The Facility for Rare Isotope Beams (FRIB) officially began operations and started its user program in May. A ribbon-cutting ceremony was held May 2, 2022 to officially mark the “start of FRIB’s scientific mission” with U. S. Secretary of Energy Jennifer Granholm and the president of Michigan State University Samuel Stanley in attendance. The first […]
