Grid-Focused Diodes for Radiography

Abstract

Simulations with the TRAK ray-tracing code have shown that grid-focused diodes might be a simple alternative to gas/plasma cell focusing for moderate-energy radiography machines. Multi-grid focusing has advantages over single grid focusing, especially in circumventing neutralization from gases evolved from the heated target. The practical technology for grid focusing was established many years ago in an extensive series of experiments.
