Abstract
Abstract
The CONCERTO spectral-imaging instrument was installed at
the Atacama Pathfinder EXperiment (APEX) 12-meter telescope in April
2021. It has been designed to look at radiation emitted by ionised
carbon atoms, [CII], and use the “intensity Mapping” technique to
set the first constraints on the power spectrum of dusty
star-forming galaxies. The instrument features two arrays of 2152
pixels constituted of Lumped Element Kinetic Inductance Detectors
(LEKID) operated at cryogenic temperatures, cold optics and a fast
Fourier Transform Spectrometer (FTS). To readout and operate the
instrument, a newly designed electronic system hosted in five
microTCA crates and composed of twelve readout boards and two
control boards was designed and commissioned. The architecture and
the performances are presented in this paper.
