Herschel Hardware and Software
Arcetri research teams have contributed to the
Heterodyne Instrument for the Far Infrared
(PI: F. Helmich, SRON, Groningen, The Netherlands)
and to the calibration of
Photodetector Array Camera and Spectrometer
(PI: A. Poglitsch, MPE, Garching, Germany).
An Arcetri scientist also participates in the Instrument Control Center
within the context of the HIFI reduction pipeline.

The photometric and spectral calibration of PACS, the 50-250 micron
imager/spectrometer on board Herschel was done in collaboration with Arcetri.
In early 2006 a test calibration was
performed in Florence with satisfactory results. After further improvements and
fine tuning, in September 2006 the apparatus was transported to the MPE in
Garching where the calibration of the Flight Model was successfully performed.
The Spare Model calibration will be accomplished in 2009.

The HIFI reduction pipeline HIPE
is being developed with the help of an Arcetri technology
scientist who collaborates closely with the HIFI instrument team in Groningen.
HIFI hardware contribution
Historically, first as CAISMI (CNR) and then as
Arcetri scientists provided a contribution to
the design and realization (in collaboration with industry) of
the Acousto-Optical WideBand Spectrometer, HIFI.
The components were delivered to KOSMA in June, 2005 and the last calibrations
in Cologne were performed in December, 2006.
