New superconducting material raises the operating temperature of space detectors

Superconducting niobium nitride (NbN) hot electron bolometers (HEBs) are so far the most sensitive heterodyne detectors for high-resolution spectroscopy at supra-terahertz frequencies (1 – 6 THz). They take advantage of a local oscillator to convert a THz line into a GHz line. Within this frequency range, many atomic, ionic, and molecular spectral lines provide information …

New methods and applications of Ptychography

Ptychography is a scanning Coherent Diffraction Imaging (CDI) method for reconstructing a complex valued object function from intensity measurements recorded in the Fraunhofer or Fresnel diffraction region. The technique provides a solution to the so-called ‘phase problem’ and is found to be very suitable for Extreme Ultraviolet (EUV) and X-ray imaging applications due to its …
