The Soft X-ray Spectrometer (SXS) is one of four instruments that will be flown on the Japanese Astro-H satellite, planned for launch in late 2015/early 2016. The SXS will perform imaging spectroscopy in the soft x-ray band using a 6x6 array of silicon microcalorimeters operated at 50 mK, cooled by an adiabatic demagnetization refrigerator (ADR). NASA/GSFC is providing the detector array and...

C-04: Space cryogenic applications
Oral presentation (15min)
The open cycle dilution refrigerator of the Planck mission had a cooling power of 0.2 $\mu$W at 100 mK during its life of 2.5 years, but future space missions (e.g. Athena+) require 1 $\mu$W of cooling power at 50 mK for a lifetime of at least 5 years.
Helium isotopes had to be stored on the Planck satellite, since the open cycle dilution refrigerator rejects the helium mixture into space...

At the University of Twente a sorption-based helium-3 pump is under development. It will be incorporated in a closed-cycle dilution refrigerator (CCDR) that is developed by the Néel institute in Grenoble. This CCDR is to be used for future long-lifetime missions requiring a cooling power of the order of 1 microWatt at typically 50 mK for at least 5 years. Crucial component in this zero-gravity...

Gauging the volume or mass of liquid propellant of a rocket vehicle in space is an important issue for its economic feasibility and optimized design of loading mass. Various gauging methods have been being explored and investigated to overcome an uneven liquid interface problem under micro-gravity. Pressure-volume-temperature (PVT) gauging method is one of the most suitable measuring...

The Space Radiation Superconducting Shield (SR2S) European project aims at studying a large superconducting toroid magnet to protect the human habitat from the ionizing radiations coming from Galactic Cosmic Ray during long term missions in deep space. Titanium clad MgB2 conductor is used to afford a bending power greater than 5 Tm at 10 K. A specific cryogenic design is needed to cool down...

The next generation of infrared space observatories will use cooled (< 6 K) telescopes in combination with ultra-sensitive cryogenic detectors to achieve background-limited sensitivity. Characterizing these detectors on the ground requires an ultra-low background cryogenic test facility with high rejection of stray light, magnetic fields and vibrations. To meet the challenge of testing such...

Thermotive LLC has developed standardized foil-type thermal straps for use in ground, air, and space applications. Furthermore, Thermotive has a new patent pending thermal strap technology called Pyrovo Pyrolytic Graphite Film (Pyrovo PGF) for the most demanding thermal control applications. Pyrovo PGF offers lighter, thinner, more flexible, and as much as 7x the thermal conductivity of...
