Superconducting Niobium/Silicon Bolometer Developments in the DCMB French Collaboration
Abstract
This paper concentrates on a first demonstrator, a 23 NbSi superconducting thermometer array, developed in the DCMB collaboration. Firstly, the NbSi thin film alloy is described then the 23 TES array topology is presented. After that, DC and noise cryogenic measurement is reported. The cryogenic readout chain is also presented and finally, the multiplexing scheme developed for the readout of the 23 pixels array is described.
