The NIKA2 instrument, operating at the IRAM 30-meters telescope, is based on the LEKID array technology dedicated to millimeter wave astronomy. This instrument is composed of one low frequency array for the 120-180GHz range, and two high frequency polarization sensitive arrays for the 220-280GHz range. Since 2013 different versions of the arrays have been developed for NIKA2. We will describe...

The NIKA2 team are continuously working on improving the performance of the NIKA2 arrays. In this talk, we present our recent developments on the 1mm array from three aspects. Firstly, a small pixel design has been studied to achieve higher angular resolution. Secondly, a thorough simulation and FTS measurements have been performed to understand the frequency response. Thirdly, a capacitor...

We are developing a 100GHz band camera designed for survey of distant galaxies. Field-of-view of this camera is around 3-arcmin, and 100GHz band observation helps peer through the characteristics of very distant galaxies. This is also a prototype for the future 10m Antarctic telescope to survey southern distant galaxies. The focal plane array of this camera is 109 pixel antenna-coupled...
