Novel method for multiturn extraction: trapping charged particles in islands of phase space.
A novel method for multiturn extraction from a circular particle accelerator is presented, based on trapping particles into islands of phase space generated by nonlinear resonances. By appropriate use of sextupoles and octupoles, stable islands can be created at small amplitude in phase space. By varying the linear tune, particles can be trapped inside these islands and then transported towards...
متن کاملAdiabatic Capture of Charged Particles in Stable Islands: a Novel Approach to Multi-Turn Extraction
Recently a novel approach has been proposed aimed at performing multi-turn extraction from a circular machine. Such an approach consists of splitting the beam by means of stable islands created in transverse phase space by nonlinear magnetic elements such as sextupoles and octupoles. Provided a slow time-variation of the linear tune is applied, adiabatic with respect to the betatron motion, the...
متن کاملPaul trapping of charged particles in aqueous solution.
We experimentally demonstrate the feasibility of an aqueous Paul trap using a proof-of-principle planar device. Radio frequency voltages are used to generate an alternating focusing/defocusing potential well in two orthogonal directions. Individual charged particles are dynamically confined into nanometer scale in space. Compared with conventional Paul traps working in frictionless vacuum, the ...
متن کاملSynthesis and Application of Novel Modified Magnetic Nanocomposite for Solid Phase Extraction of Thallium(I) Ions
In this paper, magnetically multiwalled carbon nanotubes (MMWCNTs) nanocomposite modified by methyl-2-[2-(2-2-[2-(methoxycarbonyl) phenoxy] ethoxyethoxy) ethoxy] benzoate was applied for magnetic solid-phase extraction (MSPE) of thallium(I) ions. Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), X-ray diffraction (XRD) spectrometry and vibrat...
متن کاملLarge area multiturn superfluid phase slip gyroscope
We have built and tested a large area multiturn superfluid He phase slip gyroscope. This device demonstrates quantum-mechanical phase coherence of superfluid He over a macroscopic length scale ~1.4 m!. The sensing loop area of this device is two orders of magnitude larger than our proof-of-principle model, with an improvement in sensitivity of ;20 over any other superfluid He gyroscope. We find...
