Abstract

At NAOJ, we are studying and developing wide-band receiver optics components to be used in future ALMA wide-band receivers. In particular, we are part of a consortium led by ESO for the development of a wide-band ALMA Band 2 (67-116 GHz) receiver. We have designed and characterized a corrugated horn, OMT and dielectric lens which comply with the stringent ALMA optical requirements over bands 2 and 3. For the study of the lens, we have established a quasi-optical material characterization setup to accurately measure material properties and use those results in lens designs. In addition, we are also collaborating with KASI in the development of a Band7+8 (275-500GHz) receiver. After the successful design and characterization of prototype rece...
