The cyclotron has evolved from a light-ion accelerator into a proton to uranium accelerator and has accelerated ultra-high charge state heavy ions, such as xenon and uranium. Recently, with 124Xe⁴⁹⁺ ions injected from VENUS (a 3rd generation ECR ion source) the 88-Inch Cyclotron reached a new record of ~ 2.6 GeV.* This is an energy increase of about fifteen-fold over what this K140 cyclotron could achieve when it started operation almost six decades ago. A 4th generation ECR ion source, MARS-D, is under development and will further raise the output energy of the cyclotron. With the higher ion charge states produced that are anticipated with a new ECR ion source, the 88-Inch Cyclotron ought to be able to accelerate ion beams of energies of 3 GeV and higher for the radiation effects testing community. This paper will present and discuss the development of the MARS-D ECR ion source and the 88-Inch Cyclotron’s recent and possible future achievements.
