Paper Abstract

We present the design and measurement of a direct-drillable smooth walled feedhorn for the Next Generation BLASTPol balloon experiment. Custom milling cutters were obtained commercially and used to fabricate a two feedhorn structures with UG-387 flanges, each with 0.5mm section of circular waveguide, which were then mated back to back. These horns were then tested at Cardiff University using a rotation stage scanner to measure E and H plane cuts of the horn. The measurements show good agreement in both the beam FWHM and sidelobes as compared to HFSS simulations of the horn.
