We consider an optical cavity with a light vibrating end-mirror and containing a Bose-Einstein condensate (BEC). The mediation of the cavity field induces a non-trivial interplay between the mirror an...
Design of magnet and control of the beam emittance for Penning H- ion source
H- ion source Magnetron ion source Penning ion source magnetic field gradient index
