Beam Dynamics and Control Optimal Outcome:
To conserve the Brightness of beams from extreme-low MTE linac sources subject to intense Coulomb interactions (
Conserve), increased brightness of beams in storage rings ( Cool), and advanced techniques for the optimization of many-parameter accelerators ( Control). By ensuring that CBB advances in beam production and beam acceleration are realized in brightness at the target, this theme unifies the center’s research.
