Coupling and Space Charge studies at the CERN PSB

In the nominal optics of the CERN PS-Booster (PSB), the fourth order coupling resonance is excited by space charge (Montague resonance [1]) due to the same integer tune values. This resonance can be avoided by changing the tunes to different integers. A new PSB opticsis presented and emittance measu...

Summary:In the nominal optics of the CERN PS-Booster (PSB), the fourth order coupling resonance is excited by space charge (Montague resonance [1]) due to the same integer tune values. This resonance can be avoided by changing the tunes to different integers. A new PSB opticsis presented and emittance measurements crossing the coupling resonance for the nominal and the new optics are shown.
