The ultra-high precision g-2 experiment requires a fast kicker to deflect incoming muon beam with a momentum of 3.094 Gev/c. A magnetic kicker was selected since this approach requires the lowest excitation voltage of all designs considered. However, a higher driving current (>6000A) is required which leads to more residual eddy current field to influence the main dipole magnetic field. Several...

The authors assess the role of time-dependent eddy variability in the Antarctic Circumpolar Current (ACC) in influencing warming of the Southern Ocean. For this, an eddy-resolving quasigeostrophic model of the wind-driven circulation is used, and the response of circumpolar transport, eddy kinetic energy, and eddy heat transport to changes in winds is quantified. On interannual time scales, the...

Abstract. Eddy current testing using a pickup coil is usually applied to the surface detection of cracks because of its high frequency. However, for metal infrastructure, detection of not only the surface but also internal cracks is desired. Therefore, we have developed a low-frequency eddy current testing system to inspect interior structures using a magneto-resistive (MR) sensor with a wide m...

Introduction: Clinical diffusion-weighted imaging (DWI) often employs a single-shot echo-planar imaging (EPI) readout to increase acquisition speed. This comes at a cost, however, since conventional DWI sequences employ a spin echo (SE) sequence with either unipolar or bipolar diffusion-sensitizing gradients on both sides of the 180º refocusing pulse. This configuration shortens the separation ...

The digital information revolution has brought profound changes in our society and our lives. The many advantages of digital information have also generated new challenges and new opportunities for innovation. Broadband internet and wireless network environments which have made considerable progress in recent years offer many opportunities to deliver and to exchange information. The fair uses o...

Eddy current effects can severely degrade image quality when using balanced steady-state free precession imaging with rapidly varying phase encode ordering schemes, which have common use in cardiac cine MRI. In this work, we explore and characterize a previouslyproposed technique, through-slice dephasing, as the sole technique for eddy current artifact removal. We demonstrate that artifacts var...

The California Current System is an eastern boundary upwelling system (EBUS) with high biological production along the coast. Oligotrophic offshore waters create cross-shore gradients of biological and physical properties, which are affected by intense mesoscale eddy activity. The influence of eddies on ecosystem dynamics in EBUS is still in debate. To elucidate the mechanisms that influence th...

An automated algorithm is presented for the analysis and classification of eddy current bobbin probe data obtained from nuclear power plant steam generator tubes (SGT). This algorithm attempts to find a balance between the two seemingly conflicting requirements of SGT eddy current data analysis, namely, detecting and identifying as many of the actual defects as possible, whilst limiting the num...

The influence of corrosion on ultrasonic and electromagnetic nondestructive evaluation results has been simulated for 2-layer aluminum aircraft fuselage. Simulations have been performed with respect to ultrasonic time-of-flight measurements aiming on the detection of corrosion at the backwall of the first aluminum layer. Calculations of the eddy current probe response have been performed, where...
