3 Full work plan No estoy segura de ponerla esta. Cómo lo veis? Me preocupa también qué decir sobre la financiación y perspectivas de futuro… ATHENA sensor development in Spain L.Fàbrega Utrecht, March 6 2013

4 Lab facilities  Existing CSIC laboratory network for: Deposition and lithography Structural characterization Cryogenic tests  Expertise in fabricating highest quality Mo/Au TESs Collaboration with SRON to develop absorber  Pixel testing being set Ésta está copiada (no 100%) de lo que presentamos en Ginebra el año pasado. Se os ocurre algún título/planteamiento mejor? ATHENA sensor development in Spain L.Fàbrega Utrecht, March 6 2013

5 Mo/Au bilayers d Au =115 and 215nm Typical values:  ≈ 600; R N ≈ 25m  (can be tuned without affecting T c,  ) Ésta y la siguiente las he copiado del ppt de Ginebra. Luego he añadido las I-V. Entre las 3, reproducen el póster de la ASC… ATHENA sensor development in Spain L.Fàbrega Utrecht, March 6 2013

6 Mo/Au: Stability & Homogeneity Stable when heated up to 150ºC (annealing) Homogeneous within at least 2x2cm 2 4’ wafer ATHENA sensor development in Spain L.Fàbrega Utrecht, March 6 2013

8 Work plan for 2013  Currently working on:  Fine-tuning Mo/Au deposition conditions  First tests of Bi electrochemical deposition  Tests of homogeneity over large areas (4’’)  Setup for full pixel testing (will be ready by end of june)  Fabrication of a single pixel Cooperation with SRON with design and lithography ATHENA sensor development in Spain L.Fàbrega Utrecht, March 6 2013

10 Electrodeposited Bi layers V=-0.02V t= 2.2  m V=-0.07V t= 10  m V=-0.04V t= 2  m Provisional, según si hay más resultados Al menos habría que añadir  y tamaño grano de éstas ATHENA sensor development in Spain L.Fàbrega Utrecht, March 6 2013

11 Pixel design Significant differences between SRON (Ti/Au) and GSFC (Mo/Au): Need for banks or fingers? Absorber material and shape? Are these conditioned by TES’s material? Start with SRON design and further test/optimize

12 Conclusions Pixel design and fabrication under way (with the help of SRON) Pixel characterization setup to be ready mid- 2013 Homogeneity tests previous to array fabrication under way Funding garanted for 2013+ XMS development plan necessary to obtain funding for next phases Sensor development by XMS-ESP ATHENA sensor development in Spain L.Fàbrega Utrecht, March 6 2013
