Prototype high angular resolution LEKIDs for NIKA2

Abstract

The current resolution of the NIKA2 260 GHz arrays is limited by the $1.6\times 1.5m{m}^2$ inductor size on the individual pixels. In view of future updates of the instrument, we have developed a prototype array with smaller pixels that is experimentally compared to the current pixel design. We find an in-lab improvement increase of the angular resolution of 8%, promising an on-sky FWHM resolution of 10.2" using this new pixel design.
