Studies of the longitudinal beam dynamics in the small isochronous ring (SIR) at Michigan State University revealed a fast, space-charge driven instability that did not fit the model of the negative mass instability. The observed beam behavior can be

We use the ponderomotive potential of the rf field to accurately describe the motion of ions in an rf gun. We apply the method to the BNL 1/2-cell superconducting radio-frequency photogun and demonstrate that a significant portion of ions produced in

Ion back bombardment is believed to be a main cause of degradation of quantum efficiency of photocathodes in fixed-voltage photoguns. Ions produced in collisions of the electron beam with residual gas in the cathode-anode gap are accelerated towards

In this paper, a formula, describing the threshold of regenerative multipass beam breakup (BBU) for a single dipole higher-order mode with arbitrary polarization in a two-pass accelerator with a general-form, 4×4 recirculation matrix, is derived. A

Fermilab Booster synchrotron requires an intensity upgrade from 4.5x1012 to 6.5x1012 protons per pulse as a part of Fermilab's Proton Improvement Plan-II (PIP-II). One of the factors which may limit the high-intensity performance is the fast transver
