Thermal-imaging camera tubes with pyroelectric targets
Pyroelectric targets for thermal television can have broad spectral bandwidth, fast response to chopped signals and can operate uncooled. Analysis shows that targets of triglycine sulphate (TGS) are capable of good spatial resolution and high responsivity in practical thicknesses. The noise sources and constraints for electron beam readout in both cathode-potential and anode-potential stabilize...
متن کاملCharge amplification concepts for direction-sensitive dark matter detectors
Direction measurement of weakly interacting massive particles in time-projection chambers can provide definite evidence of their existence and help to determine their properties. This article demonstrates several concepts for charge amplification in time-projection chambers that can be used in direction-sensitive dark matter search experiments. We demonstrate reconstruction of the “head-tail”ef...
متن کاملHarvesting Nanoscale Thermal Radiation Using Pyroelectric Materials
Pyroelectric energy conversion offers a way to convert waste heat directly into electricity. It makes use of the pyroelectric effect to create a flow of charge to or from the surface of a material as a result of heating or cooling. However, an existing pyroelectric energy converter can only operate at low frequencies due to a relatively small convective heat transfer rate between the pyroelectr...
متن کاملElectron emission channeling with position-sensitive detectors
Electron emission channeling allows direct lattice location studies of low doses of radioactive atoms implanted in single crystals. For that purpose the anisotropic emission yield of conversion electrons from the crystal surface is measured, most conveniently by use of position-sensitive detectors. We discuss characteristic features of this method, including quantitative data analysis procedure...
متن کاملEnergy-sensitive cryogenic detectors for high-mass biomolecule mass spectrometry.
Energy-sensitive calorimetric detectors that operate at low temperatures ("cryogenic detectors") have recently been applied for the first time as ion detectors in time-of-flight mass spectrometry. Compared to conventional, ionization-based detectors, which rely on secondary electron formation or the charge created in a semiconductor, cryogenic detectors measure low-energy solid state excitation...
