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

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.
