A study of the influence of the discharge gap length and the initial gas pressure on the energy deposition into the discharge channel was done. The study was conducted at the same total discharge energy. It is experimentally shown that the connection of the voltage probe to the discharge circuit significantly affects the discharge current. The determination of the energy deposited into the spark channel is based on the results of numerical simulation of the spark channel development. Experimentally measured discharge currents at different pressures and the gap length were used as initial data for the calculation. Based on the obtained results, it is determined which of the factors (the initial pressure or the gap length) has the strongest influence on the energy input into the spark channel.

This chapter provides a method for organizing a portal channel development strategy by identifying potential content, classifying it and then prioritizing it into distinct categories. Several effective ways of identifying content are discussed that include committees, focus groups and pilot projects. Representatives of the campus communities that will be using the portal are important to poll, ensuring they describe their actual needs versus what they think they need. External resources aggregated into the portal must be appropriate to the institution and reliable. Channels that streamline your institution’s business processes will be the most valuable parts of your portal; the bulk of your portal development work should be spent in creating them. Understanding your portal vendor’s programming interfaces to create custom, integrated applications is vital, as well as their philosophy in distributing new portal channels.
