The Berkeley Lab Laser Accelerator (BELLA) Center focuses on the development and application of laser-plasma accelerators (LPAs). LPAs produce ultrahigh accelerating fields (1-100 GV/m) and may provide a compact technology for a variety of applications that include accelerators for high energy physics and drivers for high energy photon sources. We routinely produce femtosecond electron bunches in our lab with energies ranging from 1 MeV to beyond 1 GeV using mm- to cm- scale plasma structures. Experimentally and theoretically, we study the interaction of intense laser pulses with gas, plasma and solid targets, with applications to advanced accelerators and novel radiation sources. Experiments are centered around the state-of-the-art BELLA petawatt laser facility, which provides 40 J pulses of 40 fs duration at a repetition rate of 1 Hz, as well as 10-60 terawatt (0.5-2.5 joule) systems at 10 Hz, and offers shielded target areas and diagnostics. The BELLA Center is part of the Accelerator Technology and Applied Physics Division of the Lawrence Berkeley National Laboratory. |

The interaction of extremely intense laser pulses with solids, liquids and gases has many technological applications and is rich in physics. Our experiments involve elements of atomic physics, nonlinear optics, plasma physics, condensed matter physics and quantum electronics. There are two conditions generated in our laser-matter interaction experiments that make many of the applications possible, and motivate much of the physics interest. The first is that intense lasers can locally heat up matter to about 100 times the temperature of the sun. This means that such heated material is a strong x-ray source. The second is that high laser intensities, the optical properties of materials behave in altogether new ways. For example, at laser intensities greater than about 1018 W/cm2 (routinely generated in our lab), one must consider relativistic corrections to the index of refraction! Such effects make possible exotic laser-driven particle acceleration schemes, which have the aim of shrinking existing multi-kilometer long particle accelerators to the size of a table top. |

We are testing the breakdown rate of copper and hybrid (copper plus dielectric) structures at accelerating gradients up to 100 MV/m. Information on breakdown rate is critical to planning future high energy accelerators. We also conduct research on high power microwave sources using the electron beam from a 500 kV, 80A electron gun. We have built a 10 MW, 2.856 GHz, microsecond pulse length backward wave oscillator that utilizes a metamaterial structure, consisting of a periodic array of split ring resonators. |

SLAC test facilities include FACET (Facility for Advanced Accelerator Experimental Tests) and NLCTA (Next Linear Collider Test Accelerator). FACET is a user facility for beam-driven plasma and dielectric wakefield acceleration studies, and has the unique capability of providing high-current (up to 20 kA) of both electrons and positrons at 20 GeV. It is currently the only facility that can study positron wakefield acceleration worldwide. Advanced accelerator work is coordinated via a broad multi-institutional wakefield collaboration. Novel experimental studies are proposed through a formal proposal process, with about four months a year of total experimental time. FACET will shut down in 2017 and FACET-II has been proposed to DOE’s Office of Science. NLCTA is a smaller facility with a 150-MeV beamline, providing a testbed for advanced light source concepts and some advanced accelerator studies, including dielectic laser acceleration. |
