Abstract :
A Transition Edge Sensor (TES) composite bolometer for Fourier Transform spectroscopy was developed. The design is based on a superconducting thermistor, SiN membrane technology and a thin film metal mesh absorber which is optimized for the spectral range from 0.1 THz to 3 THz. A prototype was built; its characterization and first application results are presented.
