Outgassing characteristics analysis of mechanical cryocooler materials

INTERPRETATION OF RGA DATA Including Observations on the Outgassing Characteristics of Materials

Effects of Outgassing from Some Materials on Gas Chamber Ageing

Several different materials that might be used for assembling Micro-strip gas chambers (MSGCs) for high luminosity experiments were tested by measuring the gain of an irradiated wire counter when each sample was put into contact with the gas upstream of the detector. The results show a fast effect on the gain of the counter for some of the materials tested, whereas others, like Stesalit, Vectra...

The Influence of Ultrafine Filler Materials on Mechanical and Durability Characteristics of Concrete

This paper aims at investigating the influence of partial replacement of Portland cement with ultrafine fillers compared to limestone powder on the durability and mechanical characteristics of concrete. For this purpose, ultrafine calcium carbonate materials with different specific surface areas of 9.7 and 15.1 m2/g and limestone powder (0.72 m2/g) were used. The results indicate that the ultra...

Some Mechanical Characteristics Of Materials For Dental Prosthetics

The paper presents some researches concerning the mechanical properties of composite materials used for prosthetic dental elements. After a short introduction concerning the general strains and loads that usually apply upon prosthetic works, the authors present the virtual model of a molar tooth subjected to the most common actions, using finite element method. Then the results are further show...

Dynamic Mechanical Analysis of Cryogenic Target Materials

Adhesive strength is of critical importance for cryogenic laser-fusion targets when bonding the plasma-polymerized polystyrene copolymer plastic target shell to the support stalk (a narrow-diameter fiber of silicon carbide or Zylon PBO). Norland 68 and Dymax 921 gel, two rapid-curing, low-to-medium viscosity UV curable adhesives, are currently used for target fabrication depending on which fibe...
