Linear collective acceleration of protons by a relativistic electron beam (0.5 MeV, 50 kA, 60 ns) was explored in the vacuum diode and vacuum drift tube. Nylon meshes, polyethylene films, and nylon filaments as proton sources were tested along with the variation of cathode-anode-target spacings. Target activation was used to compare the various arrangements and to yield information concerning proton energies, amounts, and spatial distributions. Proton energies in excess of 7 MeV (12 times the electron energy) were produced with filaments in 30 cm long drift tubes. A few times 10 to the 10th power particles were accelerated at this level. Activation was localized to a target spot and an axial streak on the drift tube wall. Electron beam behavior in the drift tube was examined with a Rogowski coil to measure the current and PIN diodes to measure bremsstrahlung. In addition, the periodic activation of dielectric cathodes by radially accelerated protons is reported.
