Theoretical and experimental studies of the collective acceleration of ions by a linear
electron beam in an evacuated drift tube are presented. A one-dimensional theoretical
model of the collective acceleration process that predicts accelerated proton energies of
many times the electron-beam energy is presented. The formation of a virtual cathode
downstream of the anode-cathode gap is discussed, and the subsequent movement of the
virtual cathode downstream as the anode plasma expands allows for enhanced
acceleration of ions trapped in the potential well of the virtual cathode. Experiments
reported indicate that effective electron beam propagation and effective collective
acceleration occurs when a plasma source initially well confined to the anode is present.
