Caption: Figure 3: Temperature dependencies of the frat band voltage shift [DELTA][V.sub.FB] (1-3) and the ones of the reduced mobile ion density
[N.sub.I] (5, 6) for the MOS stacks with different values of [N.sub.ss], [cm.sup.-2] x e[V.sup.-1]: (1, 2, 4)--5 x [10.sup.11]; (3, 5)--4 x [10.sup.12].
Here, [n.sub.i] is the ion density
and is equal to the plasma density [n.sub.p], [n.sub.] is the electron beam density, e is the unit charge, r is the radial coordinate, [e.sub.r] is the radial unit vector, and [e.sub.[theta]] is the azimuthal unit vector.
[Na.sup.+] ion density
was seen to increase more slowly than that of [Cl.sup.-] ions.
of ion generating device made specifically for clinical research
The focus of ALPHA is to develop research tools to explore the intermediate ion density
regime of [10.sup.18]-[10.sup.23] ions/[cm.sup.3] (at Lawson conditions).
In order to balance the Deuterium ion density
in the chamber, ion guns are attached to the vacuum chamber.
(1964) calculated refractive index and absorption coefficient of weakly ionised air and showed that with the increase of ion density
, the refractive index decreases.
The positive ion density
was a moderate 2,700/[cm.sup.3] and the negative ion density
* determine the mechanisms and ion density
level parameters required to kill 50 percent of bacteria (LD-50) for inactivating salmonella.
where E is the electric field, q is the charge magnitude on the ions, [[Rho].sub.o] is the ion density
, N is the charge of the ion, and [Tau] is the radius of ion.
The Ulysses data indicate that the doughnut's ion density
is only half that detected by the Voyager mission.
A negative ion density
is achieved within the zone that is physically incapable of supporting air borne particles.
