Scaled experiments at the University of Maryland Electron Ring (UMER) facility have a long history of successes in understanding space-charge dynamics. Recent experiments included beam halo and losses, resonances with space-charge, longitudinal space-charge waves, solitons, and longitudinal confinement with induction cells. This talk presents progress in the design of next-generation UMER-based experimental research, with expanded capabilities to study nonlinear lattices. The work is complementary and in collaboration with the proposed IOTA ring at FNAL. UMER offers 3 advantages for this type of research: (1) the ability to assess the effects of intermediate space charge strength relevant to conventional Hadron rings on the performance on nonlinear lattices; (2) its low-cost printed-circuit magnets (enabled by the 10 keV electron beam energy) can be easily replaced to test different lattice concepts; and (3) the detailed diagnostics already in place facilitate benchmarking of simulation codes in this new regime.
