Superconducting kinetic inductance radiometer
- Electromagnetic Technology Div., National Inst. of Standards and Technology, Boulder, CO (US)
We are developing a bolometer based on a differential thermometer that senses temperature changes through changes in the kinetic inductance of a superconducting thin film. The temperature transducer is an inductance bridge patterned as an integrated circuit on a 1 cm{sup 2} Si substrate. Two inductors from opposite arms of the bridge are patterned on a 2 mm{sup 2} thermally isolated Si island which is supported by a 9 {mu}m thick Si:B membrane. The bridge is excited with audio frequency current and the bridge imbalance is detected with a commercial DC SQUID amplifier. The bridge is balanced by applying power to the thermally isolated island. This thermometer is the sensor for a prototype radiometer that will provide an absolute measure of IR power.
