A systematic study of ion and cluster ion formation in continuous supersonic planar plasma
نویسنده
چکیده
A systematic mass spectrometric survey has been performed to study ionic species that are formed in continuous supersonic planar plasma. he plasma is generated by electron impact ionization of gas that is expanded supersonically through a long and narrow slit. A quadrupole mass pectrometer is used to sample the adiabatically cooled plasma downstream for different precursor mixtures. The number of different ions and luster ions formed in the plasma is remarkably large. Densities are sufficiently high to monitor rovibrational transitions in direct absorption by unable diode laser spectroscopy, using concentration modulation and a phase sensitive detection scheme. 2007 Elsevier B.V.

Plasma Wave Acceleration of Electron in Bubble Regime in Presence of a Planar Wiggler
The plasma wave acceleration of electron in the bubble regime is investigated in a new configuration containing a planar wiggler. The space-charge field of the laser-created ion channel can focuse and stabilize the electron trajectory to guide it toward the acceleration region. The high-gradient plasma wave field can resonantly accelerate the trapped electron to higher energies in the presence ...
متن کاملDynamics of isotropic and drifting plasmas in the vicinity and within two-dimensional finite dust clusters
2D finite dust clusters are systems of small number of charged grains immersed in the plasma. The particle-in-cell (PIC) simulations are used to study the plasma structure, potential field and distributions of ion, electron and charge density within a dust cluster consisting of 19 grains in the absence and presence of a directed ion flow. In the isotropic plasma, an energetically stable configu...
متن کاملTrace Analysis of Niflumic Acid in Milk and Human Plasma by Ion-pair-based Vortex Assisted Dispersive Liquid-liquid Microextraction Combined with UV-Vis Spectrophotometry
A simple, accurate and fast vortex-assisted dispersive liquid-liquid microextraction procedure has been developed for the extractive spectrophotometric determination of niflumic acid in biological samples. The method is based on the formation of an ion association complex between niflumic acid and methylene blue. The resulting ion-pair was extracted into dichloromethane and its absorbance was m...

Background: In this study we have prepared the IgA solution from normal human plasma using plasma fractionation and ion exchange chromatography. Materials and Methods: Using fractionation of plasma with cold ethanol (starting with 8% ethanol), fraction III was prepared as a suitable source for IgA preparation. Then it was treated with caprylic acid for separation of impurities. For enrichm...
متن کاملIon beam formation in a low-pressure geometrically expanding argon plasma
Supersonic ion beam formation has been observed in a geometrically expanding low-pressure inductively coupled argon plasma. It is found that the ion beam is only observed below 3 mTorr and only when the discharge is operated in inductive mode. The geometrical expansion of the plasma induces density and potential gradients leading to the ion beam formation. The ion beam energy increases with dec...
