Abstract

Millimetre-wave astronomical observations have an enormous discovery potential for the study of the earliest stages of the evolution of the universe, clusters of galaxies, high-redshift objects, and star formation regions. One of the challenges today is to perform observations with the finest an- gular resolution, in order to accurately investigate the nature of these astrophysical sources. While for spectroscopic investigations of point-like sources ALMA is the obvious solution, for contin- uum measurements of diffuse sources large single-dish telescopes (e.g. GBT, TML, IRAM, SRT, etc.) equipped with large-format bolometeric cameras provide a much higher mapping speed. Kinetic Inductance Detectors represent an interesting option for the detector array, due to their easiness to multiplex and their capability to efficiently tackle with atmospheric issues. We are de- veloping Aluminum Lumped Element KIDs for the 3 mm atmospheric window (W-band). While interesting performance of KIDs has already been demonstrated for the 1 and 2 mm windows, further technological development is needed for their use at longer wavelengths. In this contribu- tion we will describe a recent proposal for a new KID imager to be installed at the Sardinia Radio Telescope, the largest Italian radio astronomy facility. We will discuss detector requirements and we will show the results of optical tests of the first devices
