Ionization injection of highly-charged copper ions for laser driven acceleration from ultra-thin foils

January 24, 2019

A new article from the Beg laboratory was published in Nature's Scientific Reports. The article detailed a computational study led by Dr. Jun Li , Dr. Chris McGuffey, Prof. Alexey Arefiev, and Prof. Farhat Beg of the Center for Energy Research and Department of Mechanical and Aerospace Engineering. It demonstrated the generation of quasi-monoenergetic (up to 400 MeV) and high-charge copper ions in the interaction of ultra-intense (1021 W/cm2) and short (34 fs) laser pulse with thin (20-150 nm) copper foils. The simultaneity of field ionization with ion acceleration, which we call ionization injection, is shown to be the key to the generation of high-quality ion beams in such interactions. This study offers a promising, novel mechanism to produce energetic, high-charge ion bunches for future research. This work was performed in collaboration with the Lawrence Berkeley National Laboratory and Naval Research Laboratory. The HPC resources were provided by the Texas Advanced Computing Center at the University of Texas and the Extreme Science and Engineering Discovery Environment (XSEDE). More.

 

Focused proton beams for fast ignition

January 24, 2019

In a new article featured in Laserlab Forum written by Adam Higginson, a postdoctoral researcher in Farhat Beg's lab, discusses laser research in fusion energy.  

"Researchers from British Laserlab-Europe partners the University of Strathclyde and the Central Laser Facility (CLF) have used the petawatt-class Orion laser system in the UK to produce tightly focused beams of protons, using novel shaped targets, to assess physics relevant to Inertial Confinement Fusion and to develop laserdriven proton heating for high energy density physics." More.

The November 2018 announcement of the awards program invited and encouraged nominations to recognize those faculty, staff, students, departments, and organizations who have made outstanding contributions in support of UC San Diego's commitment to inclusive excellence and diversity. A review committee comprised of representatives from the Executive Vice Chancellor and all Vice Chancellor areas evaluated nominations and recommended award recipients.

A ceremony will be held on Friday, March 1, 2019, at 1:30 p.m., at Price Center West Ballroom to recognize the recipients.  Learn more about the award.

 

CER Outreach at Fleet Science Center 2019 - On Local News!

January 15, 2019

CER Outreach members attended the Fleet Science Center's 2019 High Tech Fair at Balboa Park (January 17, from 5-8 p.m.).  At this event, students in grades 7-12 learn about opportunities available to them as they pursue a career within a scientific field in San Diego. The science that students learn in the classroom is complemented with real-life applications through interactive experiences provided by participating local STEM (science, technology, engineering and mathematics)-related industries.  CER member, Saikat Thakur, talks about high energy density science on the segement.

 

UCSD Fuel Cell Team Demonstrated Record Performance for Zirconia-Based Solid Oxide Fuel Cells

January 10, 2019

The UCSD Fuel Cell Team recently demonstrated the best cell performance for zirconia-based solid oxide fuel cells (SOFCs) at reduced temperatures (600oC-650oC vs. present operating temperatures of 750oC-800oC). Peak power densities of ~2 W/cm2 and 1.7 W/cm2 were achieved with hydrogen fuel at 650oC and 600oC, respectively. The SOFC exhibiting these extraordinary performances is a thin-film multilayer structure fabricated by a sputtering process developed by the team. More.
