A multiplexer for the AC/DC characterization of TES-based bolometers and microcalorimeters

摘要

At SRON we are developing the Frequency Domain Multiplexing (FDM) for the read-out of the TES-baseddetector array for the future infrared and X-ray space mission. We describe the performances of a multiplexerdesigned to increase the experimental throughput in the characterisation of ultra-low noise equivalent power(NEP) TES bolometers and high energy resolving power X-ray microcalorimeters arrays under ac and dc bias.We discuss the results obtained using the TiAu TES bolometers array fabricated at SRON with measured darkNEP below 5 · 10sup−19/supW/√Hz and saturation power of several fW.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
