First Results of Multi-Radiography in the Experiments with MC-1 Generator

The possibility of recording several frames on one X-ray film is investigated. This will help to reduce the number of experiments needed to obtain information on the dynamics of liner compression of cascade MC-1 generators. We developed the method to gain information on the dimensions of cylindrical structural components moving with velocities up to several km/s. We exposed the film with two or three bremsstrahlung pulses of an ironless betatron, programmable in time. The possibility of obtaining several coaxial images of a tungsten tube on one and the same film, compressed by ultra-high magnetic field pressure, is shown. Spatial resolution was good enough to determine the tube dimensions at each moment in time.
