Visualizing Patterns in the Poincaré Plot of a Magnetic Field

چکیده
In the development of magnetic fusion reactors which will be the source for future low cost power physicists must be able to analyze the magnetic fields that confine the burning plasma. The corresponding magnetic fieldlines have a periodic or quasi-periodic behavior. In this paper we describe a simple and efficient geometric technique that allows for effective visualization and topological analysis of these fieldlines through their signature in the Poincaré map.

Earth’s Magnetic Field for Spacecraft Attitude Control Applications (TECHNICAL NOTE)
In this paper the earth’s magnetic field is simulated precisely while the intensity and direction of the field are verified with one of the standard references for selected points on the earth and the results are compared with some low-order models. In another simulation, the complete model is compared with a common approximate model. The magnetic field in orbital frame is described and to empl...
متن کاملThe dependence of the magnetic field strength of a sunspot umbra on its intensity and brightness temperature
A partial decrease of the convective energy by the magnetic field of a sunspot causes the temperature of the magnetized plasma to decrease and this leads to a magneto-hydrostatic equilibrium. Thus, we expect a strong relation between magnetic field strength of a sunspot and its temperature/brightness. Here, we investigate this relation in the umbra of the large sunspot in NOAA10930 using spectr...

Introduction: Integrated radiation therapy - MRI systems are capable of delivering high doses to the target tissues near sensitive organs and achieve better therapeutic results; however, the Applied magnetic fields for imaging, can influence the charged path, change the penetration depth and deflect the particles, laterally, leading to dose distribution variations. Therefore, i...
