RADLAC-II propagation experiments

Leifeste, Gordon T.

In previous RADLAC-II beam propagation experiments, stable propagation over a Nordsieck length, in full pressure Albuquerque air (p {approximately}640 Torr) was observed. In these experiments, high transverse momentum resulted in a large equilibrium radius and thus a long betatron wavelength. Following the completion of the RADLAC-II upgrade, a new set of experiments with a small diameter (d {approximately}2 cm), high current (I {approximately}40 kA), low transverse momentum ({beta}{perpendicular} {approximately}0.2) should be possible. The development of time-resolved diagnostics, data analysis codes, and the formulation of output from theoretical calculations in a format as seen by these diagnostics in the lab continues to be a major source of effort in the program. 2 figs.
