High Mass Resolution with Magnetic Field Applied in Paul’s Trap
نویسنده
چکیده
In this paper the Paul’s trap placed in a homogeneous static magnetic field is presented. The motion of ions in such system is investigated. It is shown that such system can work in two regimes: as a mass-spectrometer and as a device which separates a particle beam depending on the mass and specific charge. An application of the external static magnetic field gives a possibility to work for a new set of parameters of the system which was not available before. Apart from that the sensitivity of the device is improved. PACS numbers: 07.75.+h, 07.77.+p

متن کاملNumerical Study of turbulent free convection of liquid metal with constant and variable properties in the presence of magnetic field
In this research, turbulent MHD convection of liquid metal with constant and variable properties is investigated numerically. The finite volume method is applied to model the fluid flow and natural convection heat transfer in a square cavity. The fluid flow and heat transfer were simulated and compared for two cases constant and variable properties. It is observed that for the case variable pro...

In this study the effect of magnetic Reynolds number variation on magnetic distribution of natural convection heat transfer in an enclosure is numerically investigated. The geometry is a two dimensional enclosure which the left wall is hot, the right wall is cold and the top and bottom walls are adiabatic. Fluid is molten sodium with Pr=0.01 and natural convection heat transfer for Rayleigh num...
متن کاملElectric and magnetic field optimization procedure for Penning trap mass spectrometers
Significant systematic errors in high-precision Penning trap mass spectrometry can result from electric and magnetic field imperfections. An experimental procedure to minimize these uncertainties is presented for the on-line Penning trap mass spectrometer ISOLTRAP, located at ISOLDE/CERN. The deviations from the ideal magnetic and electric fields are probed by measuring the cyclotron frequency ...
متن کاملScanning hall probe microscopy technique for investigation of magnetic properties
Scanning Hall Probe Microscopy (SHPM) is a scanning probe microscopy technique developed to observe and image magnetic fields locally. This method is based on application of the Hall Effect, supplied by a micro hall probe attached to the end of cantilever as a sensor. SHPM provides direct quantitative information on the magnetic state of a material and can also image magnetic induction under a...
