Paper Details

Particle accelerators can be placed in two general classes, those which operate by direct time varying electric ormagnetic fields. The following discussion will relate primarily to the direct acceleration machine where the maximumparticle energy is determined by the voltage which can be insulated. In this work, it is proposed the breakdown of air gaps ina co-axial geometry, due to the presence of metallic particle has been studied. Bare copper wire particles of different lengthshave been introduced in to a co-axial geometry and breakdown strength of air gap has been estimated. The testing high acvoltage, positive dc voltage and negative dc voltage is carried out. The study repeated with dielectric covering to the controlconductor. When a sufficiently high electric field is applied to a gas, avalanche ionization (TOWNSEND PROCESS) occurswhich will lead to breakdown. Gas insulated systems are extensively used in air insulated system due to advantages of weightand volume reduction, limited overall space requirements and easy maintenance. Even though case wise, GIS is veryexpensive has compared to AIS, it is preferred because of better service, more reliable performance and facility of higheroperating stresses. In recent years, SF6 has been considered to green house gas and hence, all round efforts are made toreduce emission of SF6 gas in to the atmosphere. This was successfully used in GITL (gas insulated transmission lines) andexperimental lines of few kilometers lengths are available
