This $240,113 federal Project Grant award, provided by the National Science Foundation (NSF) under the Mathematical and Physical Sciences program (CFDA 47.049), supports research at the California Institute of Technology (Caltech) to develop an initial conceptual design for mitigating stray light in the interferometer of the Cosmic Explorer gravitational-wave observatory. The project aims to analyze how stray light may limit the observatory's sensitivity and produce a conceptual design for the beamtube baffles to address this major noise source. Additionally, the award will produce requirements for the surface roughness of the mirrors used as test masses and explore low-scatter vacuum-compatible materials. This award is part of a series of NSF grants focused on enabling the realization of the Cosmic Explorer, a next-generation gravitational-wave observatory. The project will run from September 1, 2024, to August 31, 2027.
