The next generation of linear colliders requires peak power sourcesof-over 200 MW per meter at frequencies above 10 GHz at pulse widths of less than 100 nsec. Several power sources are under active development, including a conventional klystron with RF pulse compression, a relativistic klystron (RK) and a crossed-field amplifier. Power from one of these has(More)
The cnemophiline 'birds of paradise' (Cnemophilinae) and Macgregor's 'bird of paradise' (Macgregoria) have traditionally been included in the Paradisaeidae although their relationships within the group have been enigmatic and subject to repeated discussion in the literature. Here we use sequences from two mitochondrial genes, cytochrome b and cytochrome(More)
We use shape based searching to detect head contours of arbitrary size in single images. We begin by looking for a head model which is optimal for finding head contours of various orientations. Then we develop a search technique for finding contours of arbitrary size, and present a way in which the search space can be narrowed using color and intensity(More)
A high power cross-field amplifier is under develop ment at SLAC with the objective of providing sufficient peak power to feed a section of an X-Band (11.424 GHz) accelerator without the need for pulse compression. The CFA being designed employs a conventional distributed secondary emission cathode but a novel anode structure which consists of an array of(More)
