Increasing the accelerating potential
leads to a greater role of the processes of destruction of clusters.
where [DELTA][t.sub.s] is a normalisation time that depends on the number of the electrons in the beam ([N.sub.e]) and on the electrical power ([W.sub.T]) of the electron beam: [DELTA][t.sub.s] = e[N.sub.e][U.sub.T]/[W.sub.T], where e is the elementary electron charge and [U.sub.T] is the accelerating potential of the X-ray tube.
As indicated by the simulations, an accelerating potential in the range of 250-500 kV does not significantly affect the maximum flux of generated X-rays at the same electrical power and at the same radial distance from the symmetry axis of the conical anode.
where the electron energy [E.sub.e] has units of "eV." As indicated by formula (8), the increase in the electron energy (or accelerating potential) linearly affects the efficiency of photon generation.
The accelerating potential
is the applied voltage between the anode and cathode of the x-ray tube.
The MS analysis was performed on a Bruker Biflex III MALDI-TOF mass spectrometer operating in linear delayed-extraction mode with 19.00 kV full accelerating potential. Draw-out pulses of 1.700 kV (300-ns delay) were used for parent chain analysis.
Mass maps (100 laser shots/sample) were acquired in reflectron mode using an instrument setting of full accelerating potential of 19.00 kV, an ion-mirror voltage of 20.00 kV, and a draw-out pulse voltage of 2.65 kV (300-ns delay).
Labor markets, for example, have tightened in recent years as demand has persistently outstripped even accelerating potential
A circulating electron current in the magnetic field develops the accelerating potential
for the ions in the end-Hall source.
Four samples of polyvinyl chloride (PVC) were exposed at different accelerating potentials i.e.
Conclusion: The results showed the morphological changes on PVC samples at three different accelerating potentials for the lead ions.
