METIS is the 'Mid-infrared ELT Imager and Spectrograph' for European Extremely Large Telescope. This E-ELT instrument will cover thermal/mid-infrared wavelength range from 3 to 14 μm require cryogenic cooling of detectors optics. We present a vibration-free technology this based on sorption coolers developed at University Twente in collaboration with Dutch Space. In baseline design, has four temperature levels: N-band: detector 8 K optics 25 K; L/M-band: 40K 77 K. The latter established by...
METIS, the Mid-infrared E-ELT Imager and Spectrograph, is one of proposed instruments for European Extremely Large Telescope (E-ELT) that will cover thermal/mid-infrared wavelength range from 3-14 m. Its detectors optics require cryogenic cooling at four temperature levels, 8 K N-band detectors, 25 imager, 40 L/M-band 70 optics. To provide below K, a vibration-free technology based on sorption coolers developed University Twente in collaboration with Airbus Defence Space Netherlands B.V....
Sorption-based Joule-Thomson coolers operate vibration-free, have a potentially long life time, and cause no electromagnetic interference. Therefore, they are appealing to wide variety of applications, such as cooling low-noise amplifiers, superconducting electronics, optical detectors. The required temperature depends on the device be cooled extends into cryogenic range well below 80 K. This paper presents optimization working fluid for sorption-based JT coolers. For specific combination...
METIS is the "Mid-infrared ELT Imager and Spectrograph" for European Extremely Large Telescope (E-ELT) that will cover thermal/mid-infrared wavelength range from 3-14 micron. Starting a pumped nitrogen line at 70K, it requires cryogenic cooling of detectors optics 40 K (1.4 W), 25 (1.1 8 (0.4 W). A vibration-free technology this instrument based on sorption coolers under development University Twente in collaboration with Dutch Space. We propose sorption-based cooler three cascaded...

The formation of strain-induced martensite (SIM) is found in metastable austenitic stainless steel (m-ASS) during cold forming, and the presence SIM may cause reductions toughness, ductility, corrosion resistance m-ASS. These mechanical properties can be restored improved by proper heat treatment after however, which obviously raises manufacturing costs. One low-cost way to reduce amount m-ASS forming maintain temperature at an appropriate level. This paper intends investigate approach...
Abstract Pressure strengthening (PS) technology, also called cold stretching, is widely used to increase the allowable stress and reduce weight of cryogenic pressure vessels (CPVs) made austenitic stainless steels (ASSs). However, with taking accounts manufacturing process service environment CPVs, main source effect for yielding strength improvement still unclarified. Therefore, in this work, 9% prestrain low-temperature (−196 °C) on mechanical properties S30408 steel was comparatively...
