Part of the Nuclear Science Division, the 88-Inch Cyclotron supports ongoing research programs in nuclear structure, astrophysics, heavy element studies, and technology R&D by Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley. Major instrumentation at the 88-Inch Cyclotron include the Berkeley Gas-filled Separator (BGS), and the superconducting VENUS ion source, one of the most powerful Electron Cyclotron Resonance (ECR) ion sources in the world.

The 88-Inch Cyclotron is a 300-ton, K=140 sector-focused cyclotron with both light- and heavy-ion capabilities. Protons and other light-ions are available at high intensities (10-20 pμA) up to maximum energies of 60 MeV (protons), 65 MeV (deuterons), 170 MeV (3He), and 130 MeV (4He). Most heavy ions through uranium can be accelerated to maximum energies that vary with the mass and charge state.

The 88-Inch Cyclotron is also home to the Berkeley Accelerator Space Effects (BASE) Facility, which provides well-characterized beams of protons, heavy ions, and other medium energy particles that simulate the space environment. The National Security Space (NSS) community and researchers from other government, university, commercial, and international institutions use these beams to understand the effect of radiation on microelectronics, optics, materials, and cells.
