Abstract: A method for rapidly changing the energy shell of quantum fluctuations (ESQFs) about a mass that changes fast enough to produce time dilation and retardation between the ESQFs on opposite sides of the mass, to produce acceleration as was shown under a new quantum gravity model. The method includes, a three layered capacitor system comprising an electrostatic (ES) capacitor, i.e., a dielectric with no outer electrode, on an AC capacitor, on a DC capacitor. The AC capacitor shares an electrode on one side with the ES capacitor and on the other side with the DC capacitor. The ES capacitor has the electrodeless dielectric material surface adjacent to the upper ESQFs of the layered capacitor system and the DC capacitor has the (earth) ground surface adjacent to the lower ESQFs of the layered capacitor system. When the AC and DC voltages are applied to the layered capacitor system, an asymmetry is produced between the upper and lower ESQFs to cause acceleration on the layered capacitor system.

Abstract: An ion source having an extraction plate with a variable thickness is disclosed. The extraction plate has a protrusion on its interior or exterior surface proximate the extraction aperture. The protrusion increases the thickness of the extraction aperture in certain regions. This increases the loss area in those regions, which serves as a sink for ions and electrons. In this way, the plasma density is decreased more significantly in the regions where the extraction aperture has a greater thickness. The shape of the protrusion may be modified to achieve the desired plasma uniformity. Thus, it may be possible to create an extracted ion beam having a more uniform ion density. In some tests, the uniformity of the beam current along the width direction was improved by between 20% and 50%.
