Abstract The conductivity and strength of Cu-Fe composites are contradictory. Cryogenic treatment is a promising process to improve the materials at same time. impact cryogenic on thermo-mechanically processed Cu-11Fe composite was studied using digital micro-ohmmeter, tensile testing machine optical microscopy. average size iron grain in cryogenically treating alloy decreased distribution more...

Glazing is a process used to reduce undesirable drying or dehydration of fish during frozen or cold storage. To evaluate the effect of the time/ temperature binomial of the cryogenic frozen tunnel in the amount of glazing watera Central Composite Rotatable Design was used, with application of the Response Surface Methodology. The results reveal that the time/ temperature obtained for pink cusk-...

We report the design and construction of piezoelectric-based apparatus for applying continuously tuneable compressive and tensile strains to test samples. It can be used across a wide temperature range, including cryogenic temperatures. The achievable strain is large, so far up to 0.23% at cryogenic temperatures. The apparatus is compact and compatible with a wide variety of experimental probes...

The lead liquid argon sampling calorimeter of the SLD detector is the largest det_ector employing cryogenic liquids now in operation. This paper details the design and performance considerations, the mechanical and cryogenic systems, the absorber design and tower segmentation, the data acquisition electronics, and the control systems of the detector. The initial operational performance of the d...

We report on the present state of commissioning of the cryogenic electrostatic trap for fast ion beams (CTF) at the Max-Planck-Institut für Kernphysik in Heidelberg. The device has recently passed a cryogenic test, during which the trap was cooled down by 1.8 K superfluid helium. No leaks of the helium supply system were observed, the temperature below 10 K was reached, and the required positio...
