This brings us to the subject of standards. In this connection a standard is simply a sample with a known hydrogen content that is used for convenience to calibrate the overall counting efficiency of a particular setup, i.e., to determine the factor AfICalibration standards must be stable under irradiation. While plastic foils of known composition can be used if precautions are taken (Rudolph et al., 1986), their intrinsic instability makes them unsuitable. The standard used by most groups is hydrogen-implanted silicon, which has the advantages that it is easily prepared, the implanted dose can be measured to 5%, and the amount of implanted hydrogen is stable at room temperature and under MeV 15N irradiation, as discussed later. 

The central problem to be overcome when attempting to electroplate plastics is that generally they are good electrical insulators—they lack any intrinsic electrical conductivity. In contrast, metallic components can be cleaned and pre-treated if necessary, immersed in the plating solution, and when they are connected to a d.c. supply the coating will be produced. 

Fieldbus (data transmission only) and terminal connections of the field devices are intrinsically safe and designed to be pluggable. The power supply is fitted into a flameproof enclosure ( d ) made of plastics. Its connection... 

Among the contributions to the connection resistance described above, the intrinsic resistance of an individual conductive particle can be estimated with respect to its deformation. Since the metal-coated conductive particles are deformed plastically during the bonding process of an ACA, the numerical model for the calculation of the connection resistance should consider the plastic deformation of the conductive particles. Yim and Paik (1998) derived the connection resistance of an ACA joint from Holm s electrical contact theory, and the derived model described the connection resistance of the ACA in terms of the sample geometry, particle size, applied pressure, and the intrinsic properties of the conductive particles. However, this...
