N2 - Two separate studies of space charge longitudinal dynamics in the Los Alamos Proton Storage Ring have been completed. The first of these studies is a benchmark of a longitudinal instability caused by three ferrite inductors used in the ring to provide longitudinal space charge compensation. We use the ORBIT code to benchmark the growth time, mode spectrum, and intensity threshold of the instability. The second study concerns the 201.5 MHz linac microbunch structure of the beam. We find that this microbunch structure persists in the ring over long periods of time with no RF bunching. We show through analysis of the experimental data and simulations that space charge, coupled with energy spread effects, is responsible for the sustained structure.
