A TES Bolometer for THz FT-Spectroscopy
نویسندگان
چکیده
We recently reported on a Transition Edge Sensor (TES) composite bolometer for Fourier Transform spectroscopy which was designed, built and characterized. The design is based on a superconducting thermistor with SQUID readout, 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 noise equivalent power (NEP) of 3.8×10-13 W/Hz0.5 was achieved with a linear dynamic range of at least four orders of magnitude.

Terahertz and far infrared spectroscopy of alanine-rich peptides having variable ellipticity.
Terahertz spectra of four alanine-rich peptides with known secondary structures were studied by terahertz time domain spectroscopy (THz-TDS) and by Fourier transform infrared spectroscopy (FTIR) using a synchrotron light source and a liquid-helium cooled bolometer. At ambient temperatures the usable bandwidth was restricted to 0.2-1.5 THz by the absorbance of water. The existence of a solvation...
متن کاملTerahertz real-time imaging uncooled array based on antenna- and cavity-coupled bolometers.
The development of terahertz (THz) applications is slowed down by the availability of affordable, easy-to-use and highly sensitive detectors. CEA-Leti took up this challenge by tailoring the mature infrared (IR) bolometer technology for optimized THz sensing. The key feature of these detectors relies on the separation between electromagnetic absorption and the thermometer. For each pixel, speci...
متن کاملTime Domain Spectroscopy of Terahertz Radiation from Argon Clusters Irradiated by Intense Femtosecond Laser Pulses
The electromagnetic wave ranging from the millimeter wave to gamma ray is radiated from plasmas produced by irradiating solid and gas targets with high intensity optical pulses. The THz wave radiation from the plasmas produced by femtosecond laser pulses has been intensively studied by many groups [1-3] these few years since it is one of the promising intense THz radiation sources. Solid THz em...
متن کاملComparison of Thermal Detector Arrays for Off-Axis THz Holography and Real-Time THz Imaging
In terahertz (THz) materials science, imaging by scanning prevails when low power THz sources are used. However, the application of array detectors operating with high power THz sources is increasingly reported. We compare the imaging properties of four different array detectors that are able to record THz radiation directly. Two micro-bolometer arrays are designed for infrared imaging in the 8...
متن کاملComplex Impedance and Equivalent Bolometer Analysis of a Low Noise Bolometer for SAFARI
Transition-edge-sensor (TES) bolometers are the chosen detector technology for the SAFARI Imaging Spectrometer on the SPICA telescope. For this mission, SRON is developing bolometers, each consisting of a TiAu TES that is weakly coupled to the thermal bath through thin legs of silicon nitride. In order to understand and optimize the bolometer and to verify our detector models, we characterize t...
