A b s ~ The science objectives o f the HYDROS mission are to provide frequent, global measurements o f snrface soil moisture and surface f r d t h a w state. In order to adequately measure these geophysical quantities, the key instrument requirements were determined by the HYDROS science team to be: 1) Dualp o l a h t i o n L B a n d passive radiometer measurements at 40 km resolution, 2) Dual-...

The ALADDIN project aims at detecting warm dust populations around nearby main sequence stars. In order to achieve the significantly improved sensitivity with respect to existing instruments, the architecture of the system is focused and optimised for the mission: ALADDIN implements the nulling interferometry technique at the focal plane of a 2-telescope interferometer mounted on a rotating str...

The recent developments of the neutron scattering instruments at the DR3 10 MW steady state reactor and other related facilities at Risø National Laboratory are described. The motivation for starting these developments is to optimise the available cold and thermal neutron flux as cost effective as possible. This has led to the implementation of the RITA neutron spectrometer and the germanium mo...

The second generation Absolute Radiometer for Cosmology, Astrophysics, and Diffuse Emission (ARCADE 2) instrument is a balloon-borne experiment to measure the radiometric temperature of the cosmic microwave background and Galactic and extra-Galactic emission at six frequencies from 3 to 90 GHz. ARCADE 2 utilizes a double-nulled design where emission from the sky is compared to that from an exte...

The bone diagnostic instrument is designed to measure materials properties of bone even if it is covered with soft tissue such as periosteum, connective tissue and skin. It uses 1 a probe assembly, consisting of a reference probe that penetrates soft tissue and stops on the surface of the bone and a test probe that is inserted into the bone, 2 an actuation system that can move the test probe, t...

The SEVIRI is a 50 cm diameter aperture, line by line scanning radiometer, which provides image data in four Visible and Near InfraRed (VNIR) channels and eight InfraRed (IR) channels. The VNIR channels include the High-Resolution Visible (HRV) channel, which contains 9 broadband detection elements to scan the Earth with a 1 km sampling distance at SSP. All the other channels (including the IR ...

The description of the PESCA instrument control system is presented. The PESCA instrument has been designed and built with the purpose of studying the Solar Energetic Particles and the Anomalous Cosmic Rays from helium to iron in the energy range 1.5-50 MeV/uma and will be part of the Russian PHOTON satellite payload. The instrument comprises two different blocks: the PESCA Instrument Amplifica...
