Berkeley Lab Laser Accelerator (BELLA)[edit]

The Berkeley Lab Laser Accelerator (BELLA) is a proof-of-principle laser-plasma particle accelerator facility at the Lawrence Berkeley National Lab (LBNL). Its primary goal is to produce accelerated electron beams with an energy of 10 GeV. The BELLA project is an outgrowth of LOASIS[1] (Lasers, Optical Accelerator Systems Integrated Studies) at LBNL.



The laser at the center of BELLA has a peak power of >1.2 Petawatt with laser pulses delivered at a repetition rate of 1Hz. The laser system, produced and installed by Thales Laser Systems[2], is the first petawatt-class laser that can be operated at 1Hz or faster.
