Noise and cross-talk measurements of SAFARI FDM readout

摘要: The SAFARI instrument is a spectrometer on board SPICA, using ~4000 TES bolometers with an unprecedented sensitivity. We are currently optimizing FDM readout prototype for SAFARI, which capable of reading out 160 pixels the bias frequency range 1-4 MHz and 16 kHz spacing. present our latest results emphasis noise cross-talk performance this system. measured discussed in various configurations. also method mapping electrical between array elaborate data analysis.
