space charge

The sign of the space charge can be either negative or positive.

Consider whether capital costs should also be covered by space charges.

Capital costs were not included in any of the space charges at institutions visited.

It is also known as the space charge region.

The electrons escape from the metal and are considered space charge.

Other preferred or guaranteed positions: Extra 20% on space charge.

Space charge is an inherent property of all vacuum tubes.

Air space charges are based on weight at takeoff and distance traveled over a country.

Space charge can result from a range of phenomena, but the most important are:

A space charge develops a potential that slows the carriers down.

In addition, the potential developed by the space charge can reduce the number of carriers emitted.

The space charge grid tube was the first type of tetrode to appear.

The slowing carriers also increases the space charge density and resulting potential.

The space charge limitations for an electron monochromator are discussed too.

As a result there is no net space charge and hence no electric field.

The value of perveance indicates how significant the space charge effect is on the beam's motion.

Space charges for the first year are included in the setup costs for the database web.

The space charge created by the electron avalanches gives rise to an additional electric field.

An axial magnetic field prevents space charge spreading of the beam.

This is called the space charge effect.

In the interelectrode region, the space charge of any ions is negligible.

Emittance-dependent discrepancies, related to the longitudinal effects of the space charge, are detected.

This is to overcome space charge effects which lead to non-linearity when dealing with high current pulses.

The perveance defines the space charge limited current that can be emitted from a device.

Note that potential of the working or active electrode is space charge sensitive and this is often used.
