A novel field cage design for the CPS IPM and systematic errors in beam size and emittance

A residual gas ionization profile monitor has been recently installed in the CERN proton synchrotron. We present the design for a novel and simplified field cage structure that suppresses the secondary electrons that are induced by the ionized ions. We discuss the field cage design and the beam size...

Summary:A residual gas ionization profile monitor has been recently installed in the CERN proton synchrotron. We present the design for a novel and simplified field cage structure that suppresses the secondary electrons that are induced by the ionized ions. We discuss the field cage design and the beam size and emittance systematic error considering the non-uniformity of the fields, the space-charge effect of the beam, and the lattice parameter errors.
