Abstract :
A flash X-ray source with a high dose rate and fast risetime, but which has a low concurrent total dose, is described. Monte Carlo code predictions of dose are compared with measurements of both radiation field patterns and cross-correlation of dose in thermoluminescent detectors (TLDs) and PIN diodes. Reasonable agreement between predictions and measurements is observed for low-Z materials. Large discrepancies exist, however, for dose enhancement effects in Si from a thin Au layer.
