  • Abstract:

    The 88-Inch Cyclotron at Lawrence Berkeley National Laboratory is a sector-focused cyclotron with energy constant K of 140. The cyclotron has three electron cyclotron resonance (ECR) ion sources that have led to progressively higher intensities and charge states of heavier ions.

    The combination of cyclotron and ECR sources provide the unique ability to run “cocktails” of  ions.  A cocktail is a mixture of ions of near-identical charge-to-mass ratio.

    During the cyclotron operation, the ions are tuned out of the source together and the cyclotron acts as a charge-to-mass analyzer to separate them and provide different ion species and charge states for energy variable experiments.

    The cyclotron wideband driven RF system provides fast beam tuning, allowing users to switch back and forth between several ion species of the same cocktail with small adjustments of the accelerator frequency, so a new beam does not require retuning the whole accelerator and is obtained in one minute.

    The cyclotron supports a local research program in nuclear science and is the home of the Berkeley Accelerator Space Effects (BASE) Facility that provides well-characterized beams and simulates the space environment to understand the effect of radiation on microelectronics, optics, materials, and cells.
