The Zeeman effect has been used for measurement of magnetic fields in low-temperature plasma, but the diagnostic technique is difficult to implement in a high-temperature plasma. This paper describes new instrumentation and methodology for simultaneous measurement of the entire Doppler-broadened left and right circularly polarized Zeeman spectra in high-temperature plasmas. Measurements are mad...

During the development of ferrite-loaded accelerating cavities, the electromagnetic properties of the dispersive ferrite material need to be known. We describe a coaxial short-circuit measurement technique to measure the complex permeability of toroidal-shaped samples (127mm outer and 70mm inner diameter) that are exposed to an external magnetic bias field. The external magnetic bias field is a...

We have implemented a spectral motional Stark effect diagnostic for spatially localized measurements of magnetic field on the Gas-Dynamic Trap ~GDT! magnetic mirror device. A 7 A, 40 keV diagnostic neutral hydrogen beam was focused to a current density of 0.25 A/cm in the measurement volume, allowing achievement of a radial resolution of 4.5 cm by viewing the beam at 45° with a well-defined lig...

magnetic nanoparticles attracted a great deal of attention in the medical applications due to their unique properties. the most exceptional property of magnetic particles is their response to a magnetic force, and this property has been utilized in applications such as drug targeting, bioseparation, contrast agents in magnetic resonance imaging (mri) and heating mediators for cancer therapy. in...

A stretchable cm electromagnetic interference (EMI) measurement sheet is developed to enable the measurement of EMI distribution on the surface of electronic devices by wrapping the devices in the sheet. The sheet consists of an 8 8 coil array, a 2 V organic CMOS row decoder and a column selector, 40% stretchable interconnects with carbon nanotubes, and 0.18 m silicon CMOS circuits for electric...

Density pumpout and edge-localized mode (ELM) suppression by applied n=2 magnetic fields in low-collisionality DIII-D plasmas are shown to be correlated with the magnitude of the plasma response driven on the high-field side (HFS) of the magnetic axis but not the low-field side (LFS) midplane. These distinct responses are a direct measurement of a multimodal magnetic plasma response, with each ...

Magnetic nanoparticles have been widely used in the field of biotechnology and medicine, which has a great importance to precise and quantitative detection. This paper introduces a magnetic nanoparticles detection device of low cost, high sensitivity and real-time. When the diameter of the magnetic nanoparticles is 20nm, the third harmonic intensity of the induced voltage is in the level of mic...

MATLAB language is a quite general and high power language. Thanks to its complexity, simplicity and universality it was used anywhere in the complete study of permanent magnet force action. Main use is the control of fully automated apparatus, data acquisition and processing, numerical integration according to the models of permanent magnets, visualization of results, simulation of the dynamic...
