The Nuclear Science Division joined together with Jefferson Lab and the University of Birmingham to organize a workshop on “Silicon Pixel-based Particle Vertex and Tracking Detectors Towards the US Electron Ion Collider” Workshop. The workshop ran from September 2nd to 4th, and featured talks on the expected physics-based requirements for a silicon detector, silicon and electronics technology, and on the required ‘nuts and bolts,’ including mechanical structures, radiation damage, cooling, integration and maintenance, and even possible test beams. NSD was well represented at the workshop, with presentations by Spencer Klein (requirements to reconstruct vector mesons at an EIC), Xin Dong (secondary vertexing requirements), NSD alumni Miguel Arratia (track requirements for charged jet reconstruction), Rey Cruz Torres (all-silicon tracker layout & jet reconstruction), NSD alumni Giacomo Contin (ITS3 project and progress), Leo Greiner (infrastructure needs), Alberto Collu (power distribution), Nikki Apadula (required sites and infrastructure for assembly), Ernst Sichtermann (integration of barrel + endcaps into full silicon tracker), and Barbara Jacak (test beam opportunities at the 88″ cyclotron). The workshop concluded with a discussion on the path forward, where different routes toward silicon EIC detectors were considered. A small steering committee was formed to chart a path forward.

John Arrington has joined the RNC group. He comes to LBNL from Argonne National Laboratory, where he has been a scientist, Group Leader for Medium Energy Physics, and Deputy Division Director in Physics. His research includes hadron structure measurements at Jefferson Lab on topics such as the proton charge radius and flavor structure of nucleons. He also uses high-energy probes of nuclei to understand short-range correlations and the modification of the quark distributions of nucleons in nuclei. These studies impact nuclear structure, neutron stars, neutrino scattering, and nuclear collisions and will continue to be his focus in NSD along with building on this physics program at the future Electron-Ion Collider, where he serves as a member of the EIC Users Group Steering Committee.

The NSD welcomes Bethany Goldblum to the Nuclear Data Group, where she will perform research and development in nonproliferation and national security related projects, contribute to the scientific leadership of the Nuclear Data Group and lead a nuclear data measurement program at the 88-Inch Cyclotron. Bethany is no stranger to NSD; She comes to Berkeley Lab from the University of California, Berkeley, where she was a research engineer in the Department of Nuclear Engineering and executive director of the Nuclear Science and Security Consortium. Bethany brings expertise in low energy nuclear physics, neutron detection, and applications of machine learning in the nuclear field.

Laura Stine has joined the NSD community as a Principal Resource Analyst. She will be supporting the Physical Sciences Area; specifically, the Nuclear Sciences Division, Applied Nuclear Physics, and Office of National and Homeland Security.  Before coming to Berkeley Lab, she worked at Phacil, Inc. for 8 years where she managed various accounting functions, performed Variance Analyses, assisted with financial and government audits. She previously worked for the Alameda County Superior Court and UCSF Benioff Children’s Hospital, where she gained experience with grants, procurement and contract administration.

New NSD postdoc Rebecca Carney has joined both of the neutrino mass analysis team on the KATRIN collaboration, and the LEGEND collaboration: where she is designing and testing instrumentation for current and future upgrades. Rebecca previously worked on searching for SUSY and silicon detector instrumentation on the ATLAS experiment, most recently completing a joint PhD programme with Stockholm University and Berkeley Lab. Having previously been a part of the physics division at LBNL she is looking forward to getting to know her new colleagues in the Nuclear Science Division better!

Postdoc Shujie Li has joined the RNC group, where she will work on the Møller experiment at Jefferson Lab to measure the parity-violating asymmetry in electron-electron scattering. She received her Ph.D. from the University of New Hampshire in May, with a dissertation on “Isospin dependence of Short-range correlations in A=3 nuclei.” She is also interested in the nuclear effects on parton distributions.  She received her undergraduate degree in applied math from Sichuan University.
