Development of Arrays of Transition Edge Sensors for Application in X-ray Astronomy
At SeSens 2002, Netherlands.
Full text not available from this repository.
The development of an array of voltage biased superconducting transition edge microcalorimeters is described. This work is directed to an application in future X-ray Astronomy missions, such as Constellation-X (USA) and the X-ray Evolving Universe Spectroscopy Mission (XEUS, Europe). After several years of very successful development of single pixel microcalorimeters (SRON showed a record energy resolution ?EFWHM < 4 eV for 5.9 keV photons, combined with an effective time constant of 150 ?s and high x-ray absorption efficiency) work towards an array of 32 x 32 pixels has started. Aiming at a prototype of 5 x 5 pixels, several options for fabrication, using micromachining techniques are under study, both experimentally and theoretically. Measurement of thermal transport in detector support structures at sub-Kelvin temperatures indicates ballistic phonon transport. The detector development is accompanied by finite element modeling.
