Summary form only given. Research is underway to develop a viable technique to implement magnetic priming in the UM/Titan relativistic magnetron (-300 kV, 5-10 kA, 0.3-0.5 mus) for rapid startup and mode control. Magnetic priming involves imposing N/2 azimuthal variations in the axial magnetic field of an N-vane magnetron operating in the pi-mode. This type of magnetic priming has been demonstrated...
Summary form only given. We report experiments, theory and simulations in which the Getty, large area ECR plasma source, has been applied as a neutralizer for space propulsion applications. This plasma source utilizes linear arrays of permanent magnets, placed in the end of a large, S-band microwave horn. Magnet bars are cross-polarized so microwaves propagate through with relatively low reflection...
The authors proposed a new remote access technology, SoftWire, to provide a secure session between an intranet and a client for supporting ubiquitous office services, and secure sessions among several intranets for supporting dynamic collaboration services via the Internet. In one of the most convenient remote access system SSL-VPN, its gateway must be located in DMZ, installations and configurations...
