Active plasma resonance spectroscopy is a well known diagnostic method. Many concepts of this method are theoretically investigated and realized as a diagnostic tool. One of these tools is the impedance probe (IP), which is investigated by D.N. Walker et al.1. The application of such a probe in plasmas with pressures of only a few Pa raises the question whether kinetic effects have to be taken into...
Traditional electron spectroscopy (ES) is one of the most informative means for chemical structure analysis of the matter1. According to ES, identification of atoms and molecules is carried out by the energy analysis of characteristic electrons formed in ionization process of atoms or molecules A during collisions with particles B* of definite energy (photons, excited atoms, etc.)
Atmospheric pressure plasmas in liquid water have enjoyed much attention recently due to their ability to create vast quantities of short-lived radicals, excited species, and many other highly oxidative particles that have the ability to sterilize contaminated water. These plasmas have been shown to exhibit several distinct characteristics over a power cycle. The varying physical differences are believed...
X-ray absorption spectroscopy is a powerful diagnostic technique useful for determining the charge state, temperature and density of plasmas under a wide range of conditions and situations. It has been employed for the last two decades to measure parameters of laser produced plasmas in the high energy density (HED) regime and to measure properties of the warm dense matter. Acquiring density, temperature...
Electron spin resonance (ESR) spectrometry is the most direct and sensitive method for detecting certain reactive oxygen species (ROS)1. By ESR diagnosis, plasma-water reactions can be elucidated, which is meaningful for guiding its clinical application.
We are initiating an experiment in which time resolved visible spectroscopy will be used to characterize the plasma in and near the minidiode in aluminum (Al) X pinches. The goal of the experiment is to determine the magnetic field and other plasma conditions near the outer radius of the imploding z-pinch in the minidiode. At this location the conditions should be suitable for a magnetic field measurement...
Experimental data from gas-filled cylindrical liner z-pinch experiments is presented. The MAGPIE current (1.4 MA, 240 ns) is applied to a thin walled (80um) aluminium tube with a static gas-fill inside. The system is diagnosed axially using laser interferometry, optical streak photography and optical spectroscopy. We observe a series of cylindrically converging shock waves driven into the gas-fill...
