Abstract

The intense radiation fields generated with useful uniformity over large volumes using the novel compound-lens diode on Hermes III are characterized. The measurements show that, by changing the diode parameters, the peak dose, useful area, and useful volume of irradiation can be varied from ~100 krad(Si), ~600 cm², and ~20×10 ³ cm³ to 20 krad(Si), ~3400 cm², and ~200×10³ cm³ in a 19±2-ns radiation pulse. This versatility enables radiation fields to be tailored to a specified exposure requirement, significantly enhancing the capability of Hermes III to test radiation effects in systems
