After recent results including demonstration of narrow energy spread GeV beams, the US DOE HEP is investing in two new facilities to evaluate the applicability of plasma based accelerators to high energy physics, including development of accelerator stages relevant to a potential future plasma based collider and production of very high quality beams. The BELLA facility will comprise a 1 PW high rep rate laser and target areas to allow experiments on 10 GeV laser driven plasma wakefield accelerator stages, as well as control over injection, positron experiments, detailed beam diagnostics and radiation production. The talk could cover the designs for BELLA accelerator modules, collider concepts, the upcoming facility, and ongoing experiments to prepare the way for BELLA, including control over particle beam injection and quality, staging of multiple accelerator modules, radiation diagnostics of beam performance.
