A high brightness, low emittance photocathode rf gun is starting operation at UCLA as an injector to a 20 MeV linac. This linac will initially be used to drive FELs, plasma wakefield accelerators, and to test plasma lenses. The gun is a 1 89 cell ~r-mode standing wave structure running at 2.856 GHz, and has a copper photocathode. In the initial commissioning of the gun, photoelectron beams of u...

This research initially focused on construction of a graph database for bioinformatics — a database system allowing storage and retrieval of labeled, directed graphs. Intuitively, graph databases seem well-suited for applications like bioinformatics that involve complex, unstructured information in a fundamental way. However, it is difficult to translate graph data management research into bioi...

A ramped electron bunch (i.e. one having a current density which rises linearly from the head to the tail and then drops sharply to zero) has been predicted to be an ideal drive beam for the plasma wake field accelerator due to the large transformer ratio it is capable of generating. A scheme was recently proposed for the creation of a relativistic electron bunch that approximates a ramped curr...

Despite the growing number of studies on the acoustics of non-modal phonation, little is known about how two distinct non-modal phonations can interact acoustically when coarticulated. This study investigates the acoustics of potential breathy-to-creaky phonation contours from a production study of native speakers of English, White Hmong, and Korean. These languages differ in the nature of the ...
