Future gravitational wave detectors will be limited in sensitivity by quantum radiation pressure noise and quantum shot noise. At the AEI 10-meter prototype facility we are building a Fabry-Perot Michelson interferometer designed to meet the Standard Quantum Limit (SQL) at 200 Hz, allowing investigation into techniques to surpass this limit. One technical challenge is the use of marginally stable optical cavities. I will describe the current status, recent progress, and near-term plans of the 10-meter project, including our chosen initial configuration that will allow us to gain early experience with marginally stable cavities.
