The authors disagree with Dr. D. V. Pestrikov’s assertion that “the results obtained in the commented paper are not true,” based on how Volterra’s integral equations are treated in the paper. The authors would agree, for clarity, that the equ

This paper presents an analytical investigation of the transverse electron-proton (e-p) two-stream instability in a proton bunch propagating through a stationary electron background. The equations of motion, including damping effects, are derived for

We consider the e-p instability for long proton bunches in storage rings. We give a simplified treatment of the centroid model for the linear instability for both unbunched and bunched beams. We point out the very large resulting electron oscillation

This paper considers an intense non-neutral ion beam propagating in the z direction through a periodic-focusing quadrupole or solenoidal field with transverse focusing force, -[κ_{x}(s)xe[over ^]_{x}+κ_{y}(s)ye[over ^]_{y}], on the beam ions. Here,

We solve the problem that often arises in optics and charged particle transport design tasks of finding a time-dependent Hamiltonian system that produces a given symplectic map. In addition, we show how, given a particular Hamiltonian, to produce man

Rapidly oscillating solutions of the Vlasov–Poisson equations are required when external forces are rapidly oscillating, as occurs in focusing systems for charged particle beams. Such systems are treated using a Hamiltonian averaging technique carr
