Abstract:

This report describes an easy way to construct hemispherical grids and a procedure to cut holes of any shape through the grids without distorting the grid itself. The grid material may be either stainless steel or tungsten. The grid is made from a high transparency 100x100 screen mesh woven with 0.001 inch diameter wire. The grids are shaped and spot welded onto stainless steel annular rings. Once attached to the ring, holes of any shape may be pierced through the grid. Keywords Electron optics Ion optics.
