Issue Date: | 2016 | Volume: | Millimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy VIII | Editors: | Holland, Wayne S.; Zmuidzinas, Jonas | Series: | PROCEEDINGS OF SPIE | Number: | 9914 | First Page: | 99142X | Abstract: | ALMA is the largest radio astronomical facility in the world providing high sensitivity between 35 and 950 GHz, divided in 10 bands with fractional bandwidths between 19 and 36%. Having a lifespan of at least 30 years, ALMA carries out a permanent upgrading plan which, for the receivers, is focused on achieving better sensitivity and larger bandwidths. As result, an international consortium works on demonstrating a prototype receiver covering currents Bands 2 and 3 (67 to 116 GHz) which corresponds to a fractional bandwidth of 54%. Here we present the preliminary design, implementation and characterization of suitable refractive optics. Results indicate an excellent performance in good agreement with simulations. | Conference Name: | Millimeter, Submillimeter, and Far-Infrared Detectors and Instrumentation for Astronomy VIII | Conference Place: | Edinburgh, UK | Conference Date: | 26 June-1 July, 2016 | URI: | http://hdl.handle.net/20.500.12386/24515 | URL: | http://dx.doi.org/10.1117/12.2233143 | ISSN: | 0277-786X | ISBN: | 9781510602076 | DOI: | 10.1117/12.2233143 | Bibcode ADS: | 2016SPIE.9914E..2XT | Fulltext: | open |
