Abstract
A high-voltage electrostatic generator comprising an assembly of concentric electrically conductive half-shells (10) separated by an equatorial gap (14), essentially with cylindrical symmetry about an axis (A-A). Adjacent to the equatorial gap (14), edge regions (16) of at least a selected subset of the half-shells (20) are shaped.
Claims14
A high-voltage electrostatic generator comprising:
- an assembly of concentric electrically conductive half-shells separated by an equatorial gap, essentially with cylindrical symmetry about an axis;
- and
- adjacent to the equatorial gap, edge regions of at least a selected subset of the half-shells are shaped, such that edge regions of radially outer half-shells of the subset flare radially away from the axis, while edge regions of radially inner half-shells of the subset flare radially inwards, such that the flared edge regions are substantially aligned parallel to lines of electrostatic equipotential in the vicinity of those edge regions thereby to minimise electrostatic stress in the vicinity of the or each flared edge region.
A method of designing a high-voltage electrostatic generator comprising an assembly of concentric electrically conductive half-shells separated by an equatorial gap essentially with cylindrical symmetry about an axis and adjacent to the equatorial gap, edge regions of at least a selected subset of the half-shells are shaped, such that edge regions of radially outer half-shells of the subset flare radially away from the axis, while edge regions of radially inner half-shells of the subset flare radially inwards, such that the flared edge regions are substantially aligned parallel to lines of electrostatic equipotential in the vicinity of those edge regions thereby to minimise electrostatic stress in the vicinity of the or each flared edge region, said method comprising the steps of:
- providing to a computer, a numerical model of a starting arrangement of said half-shells;
- in said computer, numerically simulating lines of electrostatic equipotential which would be generated by the modelled arrangement in use of the electrostatic generator;
- in said computer, adapting the model to more closely align edge regions of the half-shells in the subset with corresponding lines of electrostatic equipotential, and making the adapted model available at an output of the computer in electronic form, as a data file.
