Abstract :
The SAFARI instrument is a far-infrared imaging Fourier transform spectrometer for JAXA´s SPICA mission. Taking advantage of the low emission of SPICA´s 5 K telescope, SAFARI will provide sky background-limited, Nyquist-sampled spectroscopic imaging of a 2´ × 2´ field-of-view over 34-210 μm, creating significant new possibilities for far-infrared astronomy. SAFARI´s aggressive science goals drive the development of a unique detector system combining large-format Transition Edge Sensor arrays and frequency division multiplexed SQUID readout with a high 160x multiplexing factor. The detectors and their cold readout electronics are packaged into 3 focal plane arrays that will be integrated into SAFARI´s focal plane unit. Here we present the preliminary system design and current development status of the SAFARI detector system.
