  • Emissive probe measurements of electron energy distribution function in radio-frequency plasma

    Summary form only given. A new method to measure electron energy distribution function by an emissive probe has been proposed. The method is based on measurement of the functional relationship of the floating potential and the heating voltage of emissive probe. From the measured data of the floating potential change as a function of the heating voltage, the curve of the probe collection current-voltage is analytically obtained and subsequently the electron energy distribution function is obtained by the second derivative method. The present method has several important advantages of the following: (1) it is even applicable to radio-frequency plasma in which the potentials are usually fluctuating, (2) also applicable to plasmas which are produced in non-conductive containers. In the experiment, the emissive probe 30 micrometer diameter tungsten was heated by 40 kHz pulse voltage, and the floating potential at the heating voltage off period and the floating potential difference between the heating off and on period were measured by digital oscilloscope in argon plasma. The measurements were made in both the capacitively coupled and inductively coupled plasmas. The data acquisitions were performed by GPIB and the data analysis was made with a personal computer. It was shown that the plasma electron energy probability function could be obtained without any RF compensating circuit even in capacitively coupled plasmas. In particular, since the method is very sensitive near the plasma potential, the clear depletion of the low energy electron, which has already been found and analyzed by Godyak and Piejak, could be obtained. This low energy electron depletion is due to high plasma potential. Therefore, in the inductively coupled plasma this low energy electron depletion was obtained near the induction antenna, but at the further positions from the antenna the energy distribution became Maxwellian. This feature has also been reported by Godyak recently. This change in the electron energy distribution found in ICP was very systematic with the gas pressures and the distances from the antenna. Thus the present method is quite innovative in that it is applicable to the potential fluctuating RF plasma and measurements are all done in a floating condition of probe.

  • A Measurement System to Replace the 8580

    The Radio Spectrum Measurement System (RSMS) has been used by the U.S. Department of Commerce since 1973 for gathering frequency usage data for purposes of frequency management. The HP 8580 automatic spectrum analyzer used in this mobile system is now being replaced with a more modern system. The new system will provide measurements over the 0.01-18 GHz range with bandwidths of 10 HZ to 30 MHZ. A wide-auto-ranging, and an 8568 spectrum analyzer is used in a swept-IF mode to provide high measurement efficiency with bandwidths below 1 MHZ. A separate receiver system is used for land mobile channel occupancy, which uses several rectangular bandpass filters and measurement speeds of 250 channels/second. The system will be controlled by an A600 computer with 10 M-byte disc, magnetic tape, and graphics terminal.

  • Digital Signal Processing for GNSS Receivers

    This chapter mainly focuses on the signal processing algorithms used in the physical layer of a global navigation satellite system (GNSS) receiver. It provides a general introduction of all the subsystems of a GNSS receiver. The chapter describes the first operation that a receiver performs when it is switched on: the acquisition of the satellites in view and a first estimate of certain signal in space (SIS) parameters. These estimates derive from the approximation of some results from maximum likelihood (ML) theory. Such estimates are solid, but coarse, and need to be refined by other blocks, known as tracking systems or null seekers, based on different signal processing techniques. The chapter provides a description of the gradient theory and its application in the null seekers. It shows that the estimation of the pseudoranges can be obtained after the tracking outputs are converted into navigation data, that is, when each satellite channel is in navigation mode.
