Accelerators and light sources of tomorrow

Roger Falcone, director of Berkeley Lab’s Advanced Light Source (ALS) and the Lab’s associate director for photon sciences, remarks that “the ALS was built more than 15 years ago, but a few technical advances have brought our technology up to the level of the newest machines being built in Europe today.” Progress has been so rapid, in fact, that synchrotron light sources are approaching the limits of what they can achieve in the way of short, bright pulses. For that reason, Falcone, John Corlett, and other creative scientists in the Lab’s ALS, Accelerator and Fusion Research (AFRD), and Engineering divisions are developing the technology for a new light source, of a kind known as a free electron x-ray laser.
