SPIRE, the Spectral and Photometric Imaging Receiver, is a submillimetre camera and spectrometer for the European Space Agency's Herschel Space Observatory. It comprises a three-band imaging photometer operating at 250, 360 and 520 µm, and an imaging Fourier Transform Spectrometer (FTS) covering 200-670 µm. The detectors are arrays of feedhorn-coupled NTD spider-web bolometers cooled to 0.3 K. The photometer field of view of is 4 x 8 arcmin., observed simultaneously in the three spectral bands. The FTS has an approximately circular field of view with a diameter of 2.6 arcmin., and employs a dual-beam configuration with broad-band intensity beam dividers to provide high efficiency and separated output and input ports. The spectral resolution can be adjusted between 0.04 and 2 cm -1 (resolving power of 20-1000 at 250 µm). The flight instrument is currently undergoing integration and test. The design of SPIRE is described, and the expected scientific performance is summarised, based on modelling and flight instrument test results.

“…To aid in these investigations, two software simulators have been developed: the SPIRE photometer simulator 3 (SPS) which models the photometer side of the instrument, and the Simulator for the Herschel Imaging Fourier Transform Spectrometer (SHIFTS), which models the FTS side of the instrument. 4 In this paper we will focus on the results from the photometer observing function (POF) optimisation studies. In Section 1 we outline the Herschel SPIRE system, including the observing constraints arising from an observing location of L2.…”

Optimum observing modes for the Herschel/SPIRE photometer system

2006

SPIRE is one of three instruments on board ESA's Herschel space observatory, due for launch in 2008. The instrument comprises both a photometer and Fourier transform spectrometer. The Herschel mission has a limited operational lifetime of 3.5 years and, as with all space-based facilities, has very high development and operational costs. As a result observing time is a valuable and limited resource, making efficiency of crucial importance. In this paper we present recent results derived from the SPIRE photometer simulator, detailing the optimum observing mode parameters to be employed by the Herschel/SPIRE system. We also outline the efficiency of various modes, leading to the conclusion that scan mapping is the optimal mode for the mapping of regions greater than ∼4 × 4 .

“…To accomplish these goals, SPIRE contains two sub-instruments: an imaging pho tometer and an imaging Fourier transform spectrometer (IFTS) [5]. This thesis describes the design, implementation and integration of a software simulator of the SPIRE IFTS written to generate realis tic Herschel data products based on existing subsystem qualification data [5,8]. Chapter 1 outlines the science case for the SPIRE spectrometer, describes the Herschel telescope and the motivation for the SPIRE spectrometer simulator, and provides an overview of this thesis.…”

“…To determine the power incident on the each of the 56 SPIRE bolometers at every instant in the master time grid, this module employed the simulated astronomical source (SAS; see Section 4.2) and the timelines produced by the four previous modules [5,8]. As explained in Five separate tests were conducted to characterize this module, each focusing on a differ ent component of the module.…”

The Spectral and Photometric Imaging Receiver (SPIRE) is one of three scientific instruments on the European Space Agency's (ESAs) Herschel Space Observatory (HSO). The medium resolution spectroscopic capabilities of SPIRE are provided by an imaging Fourier transform spectrometer (IFTS). A software simulator of the SPIRE IFTS was written to generate realistic data products, making use of available qualification and test data. We present the design and implementation of the simulator. Component and end-to-end simulations were compared to results from the first
