Optics and broadband anti-reflection coatings for the BA4-90/150 receiver
A. R. Polish, P. A. R. Ade, Z. Ahmed +84
The BICEP Array telescopes search for primordial B-mode polarization from inflationary gravitational waves. This signal is exceedingly faint, demanding excellent map depth and syst…

Overview and status of BICEP Array's BA4-90/150 CMB polarimeter
M. A. Petroff, P. A. R. Ade, Z. Ahmed +83
The inflation paradigm postulates a period of rapid expansion in the early Universe, which would generate gravitational waves. These tensor perturbations would produce a faint B-mo…

Multi-layer anti-reflection coats using ePTFE membrane for mm-wavelength plastic optics
Miranda Eiben, Keara Carter, Marion Dierickx +7
Future millimeter wavelength experiments aim to both increase aperture diameters and broaden bandwidths to increase the sensitivity of the receivers. These changes produce a challe…
