Berkeley Lab


Advanced Light Source Accelerator Physics

Two decades of constant improvement for a user facility


Brightness, upgraded

Since its 1991 commissioning as one of the bellwethers of the third generation of light sources, the ALS has undergone numerous enhancements. A major brightness upgrade and the introduction of “Top-off” injection are the latest enhancements that deliver photon beams of better quality and variety for the users. More >

Berkeley Lab Laser Accelerator (BELLA) Center

Driving advancement in laser-plasma accelerators


BELLA amplifiers

The LPA is a potentially revolutionary concept, now in its exciting early days, for making accelerators smaller and more affordable. The BELLA Center uses one of the world’s most powerful lasers in its campaign toward the next LPA energy landmark — 10 GeV — and is developing a variety of spinoff applications. More >

Center for Beam Physics

Accelerators and technologies for DOE and beyond


PXIE RFQ module

CBP is a central resource for theoretical and experimental innovation serving the accelerator community. Maximizing the science reach of proton accelerators at the frontiers of energy and intensity, and exploring x-ray free-electron lasers, are the two major thrusts of CBP research. More >


Tools for working on scientific grand challenges


APEX electron gun

To define and build a next-generation source of coherent, intense, ultrashort X-ray pulses to meet national needs, we are collaborating with several other laboratories in the LCLS-II project at SLAC. Key LBNL responsibilities include the injector source and magnetic “undulators” for the free-electron laser. More >

Fusion Science and NDCX-II

A user facility for “the X-Games of contemporary science”



LBNL helped pioneer the idea of using heavy-ion accelerators toward the long-term goal of inertial fusion energy, and is part of the multi-institution Heavy Ion Fusion Virtual National Laboratory. One of our facilities, an accelerator called the Neutralized Drift Compression Experiment II, along with other areas of expertise of the HIF-VNL, proved a natural match for key problems in the emergent science of high-energy-density physics with laboratory plasmas. Basic R&D toward the development of advanced materials that will be needed by the future of fusion energy is also a promising application of NDCX-II.  More >

Ion Beam Technology

Ion sources and plasmas for transformational impact


Macroparticle filter

The IBT Program integrates expertise and technologies from the deep origins of ATAP in ion-accelerator design and in the quest for fusion energy. It now supports diverse scientific and industrial applications, including quantum computing, innovative neutron and gamma generators, and improvement of everything from computer discs to energy efficient windows through plasma applications.  More >

Superconducting Magnets

Advancing a key enabling technology for HEP


End of HD2 dipole

Higher-energy colliders require ever-stronger magnets, and both quality and cost loom ever larger in importance. The Superconducting Magnet Program offers capabilities “from melt to magnet”; unequaled integration of computerized mechanical, magnetic, structural, thermal and electrical design; and a history of deep industrial collaboration.
