Digital Radiography of NIF RadHohl 09A Ta2O5 Target 54

Digital radiography data was collected for NIF RadHohl-09A Target 54 (MMED No.54, NDE No.T54). Three data sets were collected in order to: (1) characterize the relative density uniformity of the tantalum-oxide (Ta{sub 2}O{sub 5}) target material, (2) note readily-observable non-uniform features in the target, and (3) estimate the density of the target material. The Xradia Micro XCT system in B432 was used to collect the data. The system parameters were: (1) source: (a) x-ray energy = 49 kVp; and (b) power and current = 3.3 W and 66 {micro}A; (2) detector: (a) imaging optics magnifications = 4X, 20X; (b) effective pixel widths = 3.0 {micro}m (4X), 0.6 {micro}m (20X); and (c) integration time = 250 secs (5 frame-averaged 50-second integrations).
