| Résumé : |
|
We present preliminary results on characterisation of voltage biased superconducting bolometers with an NbSi alloy sensor. I(V) curves as well as complex impedance and noise measurements are carried out in a dilution fridge with a pulse tube as a first stage cooler. SQUIDs polarization and addressing are controlled by a cold ASIC in which a SiGe amplifier has been implemented. First characterisations were done on full membrane bolometers and show a noise level of about 10(-16) W/root Hz. Those detectors are developed for the QUBIC experiment, a B-modes telescope that will be deployed in Antactica in 2013 |
