2. Synchronized Beams
Time between collisions:
Ions
Electrons

3. Desynchronization Suppose ion energy set significantly lower: Ions
Electrons

4. Synchronization Option I
Ion path length change such that
Ions
Electrons

5. Synchronization Option II
Electron path length change along with ion and electron frequency adjustment such that
Electrons
Ions

6. Harmonic Jump at “Magic” Energies
Harmonic jump such that
Ions
Electrons

7. Combinations
Movement of electron and/or ion magnets (options I and/or II) 
Path length adjustment by arc movement and/or chicane(s)
Without or with harmonic jump in electron and/or ion rings
