Through experiments utilizing the Large Helical Device at the National Institute for Fusion Science, we have developed a dispersion interferometer(harmonic interferometer) which makes possible the measurement of a plasma's electron density with high accuracy.
A30:These substituents are known to increase the electron density, and the introduction of these substituents increases the electron density of the central molybdenum metal.
In both cases, it is not possible for the electromagnetic wave to penetrate into regions of the plasma where the electron density exceeds the critical electron density(around 7.6×1016 1/m3 for 2.45 GHz).
As the electron density of molybdenum increases, bonds between nitrogen atoms on the metal side and molybdenum among the nitrogen molecules coordinated to molybdenum are strengthened, and the bonds in the nitrogen molecule are weakened.
Now, using this system, when we increase the electron density in a plasma we measure the changes in the line spectrum of carbon ions.
Further, by being able to precisely measure electron density, it will now be possible to clarify through computer simulation the important behaviors of active ion species that play important roles in their interaction with living organisms and materials hazardous to the environment.
Based upon measurement, by increasing the electron density in the plasma, we also learned that there is a tendency for the speed of the flow to become large.
We have installed this harmonic interferometer to the Large Helical Device(LHD), and we have succeeded in taking highly accurate measurements of electron density in plasmas.
They have three roles, blocking unwanted reactions on the ligand, increasing the size of the ligand and donating electron density to the metal.
The fixed bias probe, which was installed to observe the small-scale electron density variation, identified significant perturbation in the electron density with several hundred Hz in the region from 97 to 120km including the region of high electron temperatures.
Novelty and originality of this research We have developed a unique plasma source that generate an atmospheric pressure plasma with a hundred times higher electron density by dielectric barrier discharge, and have already moved ahead with various applied medical research projects.
Fig. 3 Diagnostic of electron density distribution of the target plasma by the laser refracting method Energy loss of the heavy ion in plasma If several MeV heavy ion beam carries out incidence to a target, energy will mainly be given to the electron in a target.
In order to know the spatial distribution of the electron density it is necessary to know the condition of the magnetic field container through calculations. However, because the calculations take time, it is difficult to know in real time the precise condition of the container.
Time variations, such as electrical potential distribution and electron density distribution when a bipolar pulse is applied to a trench type sample are calculated by PEGASUS, and the time variation of sheath thickness is compared with the theory of Child-Langmuir.
Many studies have used the VLF device data, including ionic composition studies of the inner magnetosphere by ion cyclotron wave observation, the study of Whistler waves, broad electron density distributions in the plasma zone, and the cause of extremely low frequency(ELF) waves observed in the equatorial region.
By being able to measure electron density with high accuracy in atmospheric pressure low-temperature plasma, it is no longer necessary to rely solely upon experience and trial and error. We can produce plasmas that are optimal for application in the fields of medicine and biology.
The measurement principle is to inject a powerful laser pulse(photons) into the plasma, to measure the scattered light upon having struck electrons moving in the plasma, and then to measure both electron temperature and electron density.
This theory shows that in order to describe an N-electron system, there is no need to solve the Schroedinger equation for a wave function with 3N variables, but that it suffices to handle the electron density with 3 spatial variables.
Interferometry, which uses a laser beam, is the representative electron density diagnostic method. But in the case of atmospheric pressure low-density plasma, due to the influences of changes in the atmospheric pressure in a plasma as well as around the plasma, it was difficult to accurately measure electron density.
The higher-energy MO is anti-bonding with electron density concentrated behind each H nucleus.
