ABSTRACT (Cortinue on rever#e aide If noco emy end Identify by block number) Results are reported on the generation of MeV, pulsed ion beams at a peak power level in excess of 2 X 1011 watts that have an angular divergence of about 3040. Such beams can be used in the formation of field reversing proton rings.

Photosensitized Ultraviolet (UV) treatment is one of the best hopes for achieving the elusive goal of transferring a pulsed power application from the realm of scientific interest to commercial viability. The University of Missouri-Columbia and Clean Earth Technologies, LLC are collaborating on the optimization of photosensitized UV processes for disinfection of surfaces and liquids.

The diffusion of an external magnetic field through a toroidal conducting shell is studied under ... more The diffusion of an external magnetic field through a toroidal conducting shell is studied under the assumption of a small aspect ratio. The external magnetic field can have an arbitrary field index and magnetic flux on the minor axis of the torus. The diffused field, field index, magnetic flux and wall current are computed analytically and compared with the numerical results from the TRIDIF code. The analytical and numerical results are in good agreement. Measurements in the toroidal chamber of the modified betatron gave a delay time of 34 microseconds, which is less than 10% from the theoretical prediction fo 37 microseconds.

The device produces a unidirectional ion beam with relatively high efficiency even when the applied magnetic field exceeds the self field. This new source operates at a low, constant impedance during much of the applied voltage pulse and is better matched to available high-power, low impedance generators than previous reflexing electron devices.
