Low Temperature Detectors for Astrophysics and Particle Physics
See A Review of X-ray Microcalorimeters Based on Superconducting Transition Edge Sensors for Astrophysics and Particle Physics
The X-IFU is a 2-D imaging camera, which allows the identification and characterization of the different ionization stages in hot plasmas thanks to its excellent spectral resolution (2.5 eV at 6 keV). This enables detailed diagnostics of abundances, temperatures, densities and bulk or turbulent velocities of hot plasma in extended objects. It is an integral-field spectrometer operating in the soft X-ray band. The detector consists of an array of 3840 micro-calorimeters based on Transition Edge Sensors (TESs). The read-out is performed using Frequency Domain Multiplexing (FDM) in the 1-5 MHz bandwidth and is based on low noise Superconducting Quantum Interference Devices (SQUID) and high-Q superconducting LC resonators.
MiniGRAIL(till 2007)
The MiniGRAIL detector is a cryogenic 68 cm diameter spherical gravitational wave antenna made of CuAl(6%) alloy with a mass of 1400 Kg, a resonance frequency of 2.9 kHz and a bandwidth around 230 Hz. The quantum-limited strain sensitivity dL/L would be ~4x10-21. The antenna will operate at a temperature of 20 mK.
