We present initial results from experiments performed to characterize plastic capsules using a compact x-pinch pulser with a floor space < 1m{sup 2}. The pulser produces 80 kA current with a rise time of 40 ns. Various wire materials including tungsten, molybdenum and aluminum were used. X-pinch length was varied to obtain maximum x-ray yield and photon energies. X-rays in 5-9 keV energy range were used for the phase contrast radiography of plastic shells. Results with plastic capsules (1 mm diameter, 20 {mu}m thick wall) show a phase contrast effect at the edges of the wall. The sharpness of the image reveals source size of less than 3 {mu}m.
