Lossy surface films are known to form on diamond gyrotron windows, while thin films of TiN are intentionally deposited on alumina klystron windows to protect against multipactor. A uniform thin film of contaminant on a microwave window may absorb up to 50% of the incident power, even if the film thickness is only a small fraction of its resistive skin depth. Typical values for power losses due to surface films are on the order of 0.1%. This paper also provides the most general theoretical treatment to date on the degree of ohmic heating of discrete particulates by the rf electric field and the rf magnetic field of an electromagnetic wave, with the only assumption being that the wavelength is large in comparison with the particulate size. In general, heating by the rf magnetic field is dominant whenever the resistive skin depth is less than the radius of the particulate. The analysis may form a theoretical basis in the heating phenomenology of particulates","PeriodicalId":410776,"journal":{"name":"Conference Record of the 2006 Twenty-Seventh International Power Modulator Symposium","volume":"409 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116526505","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the focus of this research is on a surrogate for exploding wires. In this research, metallized capacitor grade-polypropylene film was used as an alternative for the traditional wire of a uniform diameter. The films that were studied have a broad variety of thicknesses ranging from 7 micron to 5 mil, lengths ranging from 5.08 cm to 19.05 cm, and sheet resistances of 1 ohm/square and 7 ohms/square. These films were used to study the effect of film properties on the transient plasma generation mechanism when exposed to a rapid high voltage discharge. The effect of these properties can be seen in the current waveform, similar to that of a uniform diameter exploding wire. By precisely understanding how the film properties affect the transient plasma formation, one can fine tune these variables to control the resulting characteristic pulse wave shape to fit a desired application.","PeriodicalId":410776,"journal":{"name":"Conference Record of the 2006 Twenty-Seventh International Power Modulator Symposium","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126845892","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Higher electron energies lead to an enhanced degree of ionization and excitation. In this paper, nanoseconds high-voltage pulses are used to drive a dielectric barrier discharge, one of the widely used methods to generate non-equilibrium, atmospheric pressure plasmas. To study the ignition process of the discharge and its structure, a high-speed ICCD camera was used. Using a 5 ns exposure time, photos showed that there are two separate discharges, referred to in this paper as the primary discharge and the secondary discharge. The first discharge starts from the bulk of the gap and the whole gap reaches its maximum emission intensity within 20 ns. Before the secondary discharge starts, there are weak emission layers next to both electrodes. The secondary discharge develops from the anode and expands towards the cathode, with the marked presence of a dark space adjacent to a weakly luminous cathode layer. Since the agents responsible for the efficient plasma reactivity are the ultraviolet (UV) photons and the chemically reactive species, the UV radiation and reactive species generation efficiency are also studied. The emission spectra shows that most of the UV is emitted by excited NO radicals, where the oxygen atoms come from residual trace amounts of air. In addition to NO and NO2 , excited N2, N2 +, OH, and He are also present in the plasma","PeriodicalId":410776,"journal":{"name":"Conference Record of the 2006 Twenty-Seventh International Power Modulator Symposium","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122228708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
