N2 - SPICA provided the next step in mid- and far-infrared astronomical
research and was a candidate of ESA's fifth medium class Cosmic Vision
mission. SAFARI is one of the spectroscopic instruments on board SPICA.
The Focal Plane Unit (FPU) design and analysis represent a challenge
both from the mechanical and thermal point of view, as the instrument is
working at cryogenic temperatures between 4.8K and 0.05K. Being a large
instrument, with a current best estimate of 148,7kg of mass, its design
will have to be optimized to fit within the missiońs mass and
volume budget. The FPU will also have to be designed for its modularity
and accessibility due to the large number of subsystems that SAFARI had
to accommodate, highlighting Fourier Transform Spectrometer Mechanism
(FTSM) and the three grating-based point source spectrometer modules
(GM) which operates at 1.7K in the FPU, the latter representing 60% of
the total mass of the instrument
