RADIOGRAPHIC X-RAY SPOT SIZE MEASUREMENT WITH BREAD PIECE
The principle of radiogr phic X-ray spot size me surement with Bread piece was presented. The output responses of the Bread piece for uniformly-distributed X-ray sources are calcul ted numerically. The rel tionship between FWHM of the response curae and the spot size is obtained. Prelimin ray experiments were performed on the inductive voltage adder (IVA),and the Bread piece is used to measure the axial spot size of the rod-pinch diode (RPD) radiogr phic source. Under the hypothesis of uniformly-distributed line source, the axial spot size value is obtained, consistent with the measuring result of the pinhole camer , verifying the applicability of the Bread piece for radiographic X-ray spot size me surement.
