Berkeley Lab


Advanced Light Source Accelerator Physics

Two decades of constant improvement for a vital 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 >

Accelerator Modeling Program

Better accelerators through advanced computing

IMPACT visualization

In ATAP’s Accelerator Modeling Program, we use advanced computing techniques to achieve fast and accurate simulations of accelerators and beams. The results benefit fields extending across much of the DOE Office of Science research portfolio and beyond. More >

Berkeley Accelerator Controls and Instrumentation Program

The eyes, ears, and hands of beam control

PIP-II RFQ linac

As both accelerators and the needs of their users become ever more subtle and precise, control and instrumentation systems must become ever more innovative and sophisticated. BACI seeks out opportunities to serve the accelerator community and advance the state of the art. 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, now being delivered, include the injector source and magnetic “undulators” for the FEL. More >

Fusion Science and NDCX-II

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



One of our heavy-ion inertial fusion energy facilities 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 this facility, called 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 and beyond


End of HD2 dipole

We lead the multi-lab, HEP-oriented US Magnet Development Program and partner with our Engineering Division in the Berkeley Center for Magnet Technology. Recent achievements include collaboration on a high-strength interaction-region quadrupole for the High Luminosity upgrade of the Large Hadron Collider (HL-LHC), as well as the magnet system for the electron cyclotron resonance ion source at the Facility for Rare Isotope Beams (FRIB).More >
