A determinação da densidade de átomos metastáveis em uma descarga de coluna positiva de argônio é obtido medindo a absorção óptica. Para obtenção de tais medidas utilizou-se dois tubos de descarga elétrica de mesma dimensão e submetidos a pressões e correntes iguais, um funcionando como lâmpada e outro como célula de absorção. Com a montagem e considerando a auto-absorção na equação que relaciona a absorção com a densidade de átomos metastáveis, mostrou-se que esta última pode ser obtida sem que haja necessidade de medir a largura a meia altura das linhas da lâmpada e do plasma. São discutidos os limites de validade do método, em particular a pressões superiores a 10 torr, onde, além da auto-absorção, deve também ser considerado o alargamento das linhas por efeito de pressão. Finalmente, a título de verificação, medidas de absorção são feitas utilizando-se uma lâmpada Phillips de argônio permitindo que se encontre a largura de linhas da lâmpada. Os valores obtidos apresentam bom acordo com valores encontrados por outros autores.

Full textA model based on space charge migration to explain an anomalous electric current peak on films of P (VDF/TrFE) copolymer in its paraelectric phase is presented. In general step-voltage current measurements of insulating polymeric materials obey the Principle of Linear Super-position. However, an unexpected anomalous peak was observed in discharge currents in measurements performed with P (VDF/TrFE) above the Curie temperature. We have assumed that space charges were dragged from the bulk of the sample by the external field during the charge measurement, and trapped close to the surface of the sample in a region where the concentration of traps would be very high. Two methods were developed to calculate the magnitude of the current peak: I) assuming a given space charge distribution during the discharge measurement, and II) considering the movement of thin discrete layers of charge under the influence of the internal field.

O estudo de descargas luminescentes no regime anormal tem merecido especial atenção devido a sua aplicabilidade nos processos de nitretação de superfícies metálicas. Um dos parâmetros importante a ser controlado no processo de nitretação é a temperatura do subtrato, por ser um fator determinante em reações químicas e processos de difusão. O nosso trabalho consiste em medir a "temperatura" rotacional dos estados N2+(B) e N2(C) do nitrogênio próxima ao cátodo, a partir da medida das intensidades relativas das linhas do espectro rotacional de emissão desses estados. As "temperaturas" rotacionais são comparadas com a temperatura do substrato que é determinada através de um termopar. É mostrado que a "temperatura" rotacional do estado N2+(B) é idêntica à temperatura do substrato exceto para descargas de nitrogênio puro a pressões superiores a 1,0 torr, enquanto que a "temperatura" rotacional do estado N2(C) é idêntica à temperatura do substrato, o que está de acordo com os resultados da literatura.

Full textIn this work we present and discuss the results obtained investigating the dynamics of the generation of the optogalvanic signal (OGS) in two types of electrical glow discharges in argon. Both discharges were operated at the subnormal regime which corresponds to the region of the volt age versus current (V x 1) curve where their dynamic resistance is negative. The typical conditions of operation for the two discharges include: a potential between 250 to 500 V across the tube, a current through the discharge of 0,1 to 1 mA, and a gas pressure of 400 to 600 Pa. In the discharge of parallel electrodes the OGS measures were performed exciting one photon transitions in the range of 415 to 434 nm with a 10 Hz pulsed laser with a pulse duration of nanoseconds. We noted that when the operation regime of the discharge varies from the normal to the subnormal one, the OGS will change its shape from a pulse to a damped harmonic oscillation. The experimental results were interpreted through a modeI that represents the discharge of parallel electrodes as a second order optoeletronic transducer. One important result of this analysis is that when the discharge changes from the normal regime to the subnormal one, the temporal evolution of the OGS (regardless of its origin) is explained modeling the discharge in terms of an electrical equivalent circuito The origin of the OGS was studied in the hollow cathode discharge through the interaction with ultrashort pulses. The measures of the intermodulated optogalvanic signal (IMOGS) in the hollow cathode discharge involved the excitation of one and two photon transitions in the range of 760 to 776 nm using a train of pair of pulses from a Ti-Sapphire laser of 76 MHz repetition rate and pulses with duration of femtoseconds. The IMOGS were recorded changing the delay 7 between the two pulses of the pair, for different values of the pulses time length. The analysis of the IMOGS was made for two regions of delays. In the region of major delays corresponding to 171> 500 fs, the dependence of the magnitude of IMOGS with the central wavelength and with the time width of the laser pulse was discussed. For the region around zero delay, that is 171 < 500 fs, his time profile was examined. We noted that the magnitude of IMOGS for major delays, which we named background leveI, depends on the resonance between the laser excitation and the one photon transitions at 763.51, 772.37 and 772.43 nm and aIso on the value of the spectral width of the pulse; more specifically, it depends on the convolution between the spectrum of the laser and one of those one photon transitions. In the analysis of the IMOGS temporal profile around the zero delay we verified that the measures could be spectrally classified into two groups: the group of signals that does not involve the photoionization and the group involving this processo To better understand the characteristics of IMOGS, we use a numerical simulation based on a 3 leveI modeI for the atom interacting with a train of ultrashort pair of pulses. The theoretical model developed presents a good qualitative agreement with the experimental data and was a useful tool for analysis and interpretation of the measures.

Full textIn the present work, results concerning the first Townsend ionization coefficient (α) in pure isobutane within the density-normalized electric field (E/N) range of 145 to 194 Td are presented. The experimental setup consists of RPC-like cell with the anode made of a high resistivity glass (2 x 1012 Ωcm) and a metallic cathode, directly connected to an electrometer, on which photoelectrons are produced by the incidence of a pulsed laser beam. The α coefficient is determined by measuring the current under primary ionization and avalanche regime. Since for the E/N range covered by this work, there are no experimental values for pure isobutane available in the literature, the obtained values were compared with Magboltz 2 results. Our studies included the determination of α coefficient for different repetition rates and laser beam intensity. The ratio of the fast charge to the total charge is related to the first Townsend coefficient, so studies concerning the ionic and the electronic contribution to the average current were also performed. Since there are few results available in the literature for isobutane, concerning collisional cross section and electron transport parameters, is common to consider results from its structural isomer: n-butane. Thus, in order to perform a comparative analysis, the coefficient α was also determined for n-butane.

Full textThe aim of this work was to construct a shunt resistor to measure impulsive currents with values from 2 kA to 100 kA, with general features similar to conventional coaxial resistors as described in the literature. However, it differs from resistors already developed because it shows many offers technological innovations. When compared to a should stand Haefely® shunt resistor, it presented great stability in all required frequency band to 10 MHz, as well as excellent temporal response.
