Paper Abstract

Open structure mixers using substrate lenses have been proposed and pioneered by (1,2). This system (fig.1) is using a lens of crystal quartz with an elliptical contour which makes a considerable difference in beam quality and cryogenic performance. It was used at the 30m antenna on Pico Veleta (Spain) in the range of 330 to 360 GHz (3). To work between 660 and 690 GHz, the mixer element was replaced and the dewar windows and the local oscillator (LO) were adjusted.
