| Bolometers cooled to very low temperature are currently the most sensitive detectors for low spectral resolutiondetection of millimetre and sub-millimetre wavelengths. The best performances of the state-of-the-art bolometers allowto reach sensitivities below the photon noise of the Cosmic Microwave Background for example. Since 2003, a frenchR&D effort called DCMB ("Developpement Concerte de Matrices de Bolometres") has been organised between differentlaboratories to develop large bolometers arrays for astrophysics observations. Funded by CNES and CNRS, it is intendedto get a coherent set of competences and equipments to develop very cold bolometers arrays by microfabrication. Twoparallel developments have been made in this collaboration based on the NbSi alloy either semi-conductive orsuperconducting depending on the proportion of Nb. Multiplexing schemes have been developed and demonstrated forthese two options. I will present the latest developments made in the DCMB collaboration and future prospects. |
