Plasma High-Density Lipoproteins
New England Journal of Medicine, 1978WHY all the recent excitement about highdensity lipoproteins (HDL)? Because of the strong inverse relation between plasma levels of HDL and mortality from cardiovascular disease.1,2 Increased serum...

The primary-electron bias voltage and the neutral-pressure dependence of plasma density in a multidipole device are investigated. Experimental data are described by a simple model which takes into account the production of multiple electron-ion pairs by each ionizing primary electron.

Edge-to-center plasma density ratio in high density plasma sources
Plasma Sources Science and Technology, 2008The flux of positive ions leaving a classical low-temperature plasma discharge is proportional to the plasma density at the plasma–sheath edge, and the edge-to-center plasma density ratio, the so-called hl factor, normally depends only on the discharge size and the neutral gas pressure.

Plasma Density Measurement by Cavity Perturbation in High Density Plasma
The Physics of Fluids, 1969A TM010, time-resolved, cavity perturbation technique has been used to measure the total number of electrons Ne in a magnetic mirror compression experiment (Te ∼ 75 keV; ne ∼ 1012−1013 cm−3; plasma length ∼ 10 cm; plasma diameter ∼ 0.5 cm; cavity length ∼ 30 cm; cavity diameter ∼ 10 cm). Ne is measured independently of the plasma density profile and in

Tailoring plasma density for laser plasma accelerators
Journal of Physics D: Applied Physics, 2009To lower the trapping threshold and partially overcome the dephasing problem, a certain axial plasma density profile is desired. To obtain such a density distribution, a laser heating method is proposed and numerically tested in this paper. By using this method, a density downramp and then upramp can be formed.
