1 STREGA M2:Advanced materials and techniques for resonant detectors (5 MIN) Participants: INFN * -Istituto Nazionale di Fisica Nucleare IFN-Istituto di Fotonica e Nanotecnologie-CNR-Sezione di Trento MiniGRAIL-Leiden University – LION Institute of Physics U-Glasgow-University of Glasgow * Involved labs: Ferrara, Firenze, Genova, Frascati, Legnaro, Napoli, Padova, Perugia, Pisa, Roma 1, Roma 2, Trento, Urbino High-performance materials can increase the sensitivity and bandwidth of resonant detectors to achieve the intended 10-fold increase in the detection capabilities. This task aims to develop knowledge of the material properties and innovative technology for the production of test masses and transducers made of these new materials. The selected materials are Molybdenum, Silicon-Carbide (SiC), Beryllium, Copper Aluminium (CuAl), Niobium. Tungsten Objectives: - Measurement of the thermal expansion, thermal conduction and mechanical losses by varying the temperature from 300K down to 0.1K. - Investigation of the fabrication processes of silicate bonding for SiC, and electron beam welding, explosion welding and cold welding for metals. - Investigation of the various metal production processes as well as low temperature calorimetric studies to choose metals with the smallest Hydrogen contamination.
