  • 1985–1989
    - electrostatic version
    - spiral quadrupoles
    - equipotential lenses
    - electrostatic correction plates
    - not installed on the cyclotron


  • 1990–1995 (GA ČR 102/94/0364)
    - magnetostatic version
    - solenoids with Fe structure i.e.  B – channel
    - spiral inflector
    - two gap first harmonic buncher
    - ion source CUSP (TRIUMF) 1.3 mA of DC H− ions
    - Li ion source (modified Duoplasmatron, Li+3 (low beam intensities)
    - In operation on the cyclotron
