Objective
Research objectives and content We propose a new design of high energy resolution detectors for X-ray astronomy. An array of sub-millimetric-sized superconducting devices, which define a position resolution better than l50um, cover the detector area (several square centimetres). Photons are absorbed in such devices, and detected by measuring the excess of quasi-particles created. Quasi-particles are trapped in a tungsten thermometer where they loose energy, increasing the temperature of the electron bath. The tungsten thermometer, operating near the superconducting transition temperature (Tc=l5mK) transforms the temperature increase into a rise in resistance. Taking advantage of the fast quasi-particle diffusion in the absorber and the low heat capacity of the thermometer, we believe that an energy resolution high as lOeV, which is at least a factor ten higher than the best silicon-based detectors, can be achieved. The development of small cryogenic refrigerators, reaching temperatures as low as 5mK, will allow these detectors to be used in space. Training content (objective, benefit and expected impact) Training on dilution refrigerators and instrumentation electronics will be necessary. In particular, the achievement of a low baseline electronic noise is needed in high-energy resolution detectors. Links with industry / industrial relevance (22) Although no direct links with industry are involved in this proposal, the development of high- resolution X-ray detectors is of strong interest to industry.
