Zerolength Multipole RF DeFlector from dipole to decapole
Parameter Name  Units  Type  Default  Description 
END_PID  long  1  If nonnegative, highest particle ID to which deflection is applied. 

GROUP  string  NULL  Optionally used to assign an element to a group, with a userdefined name. Group names will appear in the parameter output file in the column ElementGroup 

This element simulates an rf deflector with specified multipole content.
Assuming for simplicity that y = 0, the momentum change in the horizontal plane is
 (97) 
where k = ω∕c and p_{x} = β_{x}γ. The deflection is
 (98) 
where the approximation results from the fact that p_{z} = β_{z}γ also changes in order to satisfy Maxwell’s equations.
