An experimental facility is described which has been designed to perform ultrafast two- and three-dimensional electron beam computed tomography. As a novelty a specially designed transparent target enables tomography with no axial offset for 2D imaging and high axial resolution three-dimensional im-aging employing the cone-beam tomography principles. The imaging speed is 10,000 frames per second for planar scanning and more than 1000 frames per second for 3D imaging. The facility serves a broad spectrum of potential applications primarily the study of multiphase flows, but also in principle non-destructive testing or small animal imaging. In order to demonstrate the aptitude for these applications static phantom experiments at a frame rate of 2000 fps were performed. Resulting spatial resolution was found to be 1.2 mm and better for a reduced temporal resolution.
