RHIC VERTICAL AC DIPOLE COMMISSIONING.
2002-06-02

The RHIC vertical ac dipole was installed in the summer of 2001. The magnet is located in the interaction region between sector 3 and sector 4 common to both beams. The resonant frequency of the ac dipole was first configured to be around half of the beam revolution frequency to act as a spin flipper. At the end of the RHIC 2002 run, the ...

Fluid flow induced by nonuniform ac electric fields in electrolytes on microelectrodes. I. Experimental measurements
2000-04-01

Under the influence of an ac electric field, electrolytes on planar microelectrodes exhibit fluid flow. The nonuniform electric field generated by the electrodes interacts with the suspending fluid through a number of mechanisms, giving rise to body forces and fluid flow. This paper presents the detailed experimental measurements of the velocity of fluid flow on ...

Signal transmission from cones to amacrine cells in dark- and light-adapted tiger salamander retina.

Amacrine cells (ACs) are third-order interneurons in the retina that mediate antagonistic surround inputs to retinal ganglion cells and motion-related signals in the inner retina. Previous studies have revealed that rod-to-AC signals in dark-adapted retina are mediated by a nonlinear high-gain synaptic pathway. In this study, we investigated how cone ...

When an AC electric field was applied across a small gap between two metal electrodes elevated above a surface, rhodamine-phalloidin-labeled actin filaments were attracted to the gap and became suspended between the two electrodes. The variance ?s2(x)? of each filament's horizontal, lateral displacement was measured as a function of electric field ...

The AC dipole is a device to study beam optics of hadron synchrotrons. It can produce sustained large amplitude oscillations with virtually no emittance growth. A vertical AC dipole for the Tevatron is recently implemented and a maximum oscillation amplitude of 2{sigma} (4{sigma}) at 980 GeV (150 GeV) is achieved [1]. When such large oscillations are ...

Initial tests of an AC dipole for the Tevatron
2006-06-01

The AC dipole is a device to diagnose transverse motions of a beam. It can achieve large-amplitude oscillations without two inevitable problems of conventional kicker/pinger magnets: decoherence and emittance growth. While not the first synchrotron to operate with an AC dipole, the Tevatron can now make use of its recently upgraded BPM system, providing ...

Depinning of flux lines and AC losses in magnet-superconductor levitation system
1999-11-29

The AC loss characteristics of a magnet-superconductor system were studied with the magnet fixed to the free end of an oscillating cantilever located near a stationary melt-textured YBCO pellet. Below a threshold AC field amplitude {approx}2Oe, the dissipation of the oscillator is amplitude-independent, characteristic of a linear, ...

We present measurements of AC losses in Bi-2223 multi-pancakes coils with different geometries. Measurements were performed at 77 K at frequencies ranging from 50 to 1600 Hz. The losses are found to depend strongly on coil configuration and linearly increase with increasing frequency. The centre pancakes in the coils exhibit larger AC ...
