Plasma chemistry of fluorocarbons as related to plasma etching and plasma polymerization

1981
This chapter deals with the physical and chemical processes which take place in fluorocarbon plasmas. Emphasis is given to plasma diagnostic techniques which are well suited to investigate the neutral and ionized gas phase species as well as plasma-surface interactions.

Effects of Plasma Boundaries in Plasma Oscillations

Physical Review, 1950
The discussion of electron plasma oscillations is extended to include some of the effects of boundaries. It is first shown that an electron taking part in a traveling plasma oscillation will be reflected at a sheath of infinitesimal thickness with velocity appropriate to the oscillation traveling in the reverse direction. This means that standing waves

Human Blood Plasma and Plasma Substances

AJN, American Journal of Nursing, 1954
LMOST from the beginning of history, the importance of blood was appreciated and it was believed to have mysterious properties which could be transferred from a donor to a recipient. Although transfusion is an old procedure, no degree of success was attained until the beginning of the present century when Crile, Elsberg, and others developed methods ...

Clinical use of plasma and plasma fractions

Best Practice & Research Clinical Haematology, 2006
The use of plasma and plasma-derived products has always involved a careful balance of anticipated benefit versus risk. Risk reduction through pathogen-inactivated products has been successful, but the expense of manufacture does not warrant widespread use.

Effect of plasma nonlinearity on the beam-plasma interaction in a hybrid plasma waveguide

Plasma Physics Reports, 2001
A study is made of the characteristic features of the effect of plasma nonlinearity in a slow-wave structure on microwave generation by an electron beam and on electron beam energy losses. Theoretical results on the plasma density variation, the amplitude of the excited microwaves, and the velocity distribution function of the beam electrons are ...

Plasma waves in a nonideal plasma

Journal of Experimental and Theoretical Physics, 1998
This paper shows how the concepts commonly used for a Debye plasma—Landau damping, collisional damping, short-range and long-range collisions, and plasma waves—must be revised to describe a nonideal electron-ion plasma. The degrees of freedom of a nonideal plasma are divided into collective and individual. The increase and saturation of the fraction of

Transverse Plasma Waves and Plasma Vortices

Physical Review, 1958
Plasmas at high-electron temperatures can carry transverse waves in which self-magnetic fields and relativistic effects become important. The relativistic perturbation equations for an isotropic uniform plasma are solved as an initial-value problem, i.e., by Laplace transformation and the propagation or dispersal of both longitudinal and transverse ...

Plasma crystals and liquid plasmas

AIP Conference Proceedings, 1998
General properties of strongly coupled colloidal plasmas are briefly summarised, and their properties of being able to “condense” into a self-organised liquid and crystalline form is discussed. Both laboratory and microgravity aspects of the research into this new form of matter are described and the theoretical constraints are compared with available ...

Plasma-Electron Resonance, Plasma Resonance and Plasma Shape

Physical Review, 1931
Plasma-electron resonance is a completely internal oscillation in a plasma and has a frequency dependent only on the electron density, whereas plasma resonance depends upon boundary conditions as well. The frequency of neither is influenced by the Debye-H\"uckel ion cloud. Previous theory relating plasma-resonance frequency to plasma shape is amplified
