IASF Roma - STATUS REPORTfor the Visiting CommitteeRef: IASF-RM-VC-001/07DATA: 19 November 2007Page: 47/134The AGILE Test and Calibration in RomeThe AGILE satellite payload during calibration in Rome and QLF tests in Munich (IABG)Cryogenic Laboratory for X-ray microcalorimeterThe cryogenics Laboratory for microcalorimeter is equipped with a dry cryogenic system (withoutcryogenic liquids) for reaching temperature around 30mK. This refrigeration, realized by Germancompany Vericold, is a combination between pulse-tube and ADR (Adiabatic DemagnetizationRefrigerator), similar to the cryostats that will be used in the next spatial missions. The refrigerationwill be used to cool down TES microcalorimeter models, the most recent generation of soft X-Raydetectors, to reach E/DE>1000, high could-rate and quantum efficiencies. The prototype (singlepixel and in array 2x2) will be realized by INFN-Genova University, then tested and customised inour IASF Rome Laboratory. In addition to the necessary equipment for the functioning of thecryostat, the laboratory has already in part supplied of the necessary electronic equipment for thisactivity: calibration source, low noise amplify, acquisition card, and more recent amplificationsystem based on superconducting called SQUID (Superconducting Quantum Interference Device).In collaboration with IFN-CNR and AAS-Laben, electronic preamplifier system are tested anddeveloped that are capable of working in low temperature (4K). A small clean zone will be presentin the laboratory to execute works that require a moderately clean environment.47
