A stand-alone magnetic guide for producing tuneable radical beams

A hexapole magnetic guide for neutral atomic beams.

In this paper we present a multiple element magnetic device to guide atoms using a spatially inhomogeneous magnetic field formed by a series of permanent hexapole magnets. The operation of the device is demonstrated using an enhanced beam of neon atoms in the 3P2 metastable state. These atoms are guided around a bend of 30 degrees from their original path. A flux of 4.35 x 10(9) +/- 2 x 10(7) a...

A Framework for Developing Stand-Alone Certifiers

Current tools for automated deduction are often powerful and complex. Due to their complexity there is a risk that they contain bugs and thus deliver wrong results. To ensure reliability of these tools, one possibility is to develop certifiers which check the results of tools with the help of a trusted proof assistant. We present a framework which illustrates the essential steps to develop stan...

Stand-alone mass media campaigns to increase physical activity: a Community Guide updated review.

CONTEXT The goal of the systematic review described in this summary was to determine the effectiveness of stand-alone mass media campaigns to increase physical activity at the population level. This systematic review is an update of a Community Guide systematic review and Community Preventive Services Task Force recommendation completed in 2001. EVIDENCE ACQUISITION Updated searches for liter...

Direct Flux Control for Stand-Alone Operation

In this paper, a novel voltage control strategy of stand-alone operation brushless doubly 9 fed induction generator for variable speed constant frequency wind energy conversion systems 10 was presented and discussed particularly. Based on the model of the generator power system, the 11 proposed direct flux control strategy employs a nonlinear reduced-order generalized integrator 12 based resona...
