Finite Element Analysis of Defibrillation Current Density in Pregnant Women

A. Jeremic[1], E. Khosrowshahli[1]
[1]McMaster University, Hamilton, ON, Canada

Although resuscitation during pregnancy is relatively uncommon and rarely causes death, they have a particularly large impact in terms of the mortality of the unborn child and long-term effects on families and society as whole. In this paper, we present a new 3D finite element model of a ... Mehr lesen

Investigation of a Hybrid Winding Concept for Toroidal Inductors Using 3D Finite Element Modeling

[1]Department of Physics, Royal Military College of Canada, Kingston, ON, Canada
[2]Department of Physics, Engineering Physics and Astronomy, Queen's University, Kingston, ON, Canada

Steam generator (SG) tubes in CANDU® nuclear reactors can lose efficiency in the presence of corrosion and its by-products. Condition monitoring of support structures could help direct maintenance activities and thereby increase SG tube lifetime. Pulsed eddy current (PEC) has been ... Mehr lesen

Chemical Reaction Under Highly Precise Microwave Irradiation

S. Fujii[1], Y. Wada[2]
[1]Chiba University, Chiba, Japan
[2]Tokyo Institute of Technology, Tokyo, Japan

Chemical reactions conducted under microwave irradiation have high reaction rates and high selectivity, but these reaction rates are not always reproducible. To achieve reproducibility, a solid-state microwave source with an ultra precise oscillator, high power amplifier module (HPA), ... Mehr lesen

Optimization of Mechanical Properties of Superconducting Cavities for Project X LINAC

I. Gonin[1], M. Awida[1], T. Khabiboulline[1], V. Yakovlev[1]
[1]Fermilab, Batavia, IL, USA

Project X is a proposed proton accelerator complex at Fermilab. The CW LINAC is based on five types of resonators operating at three frequencies: half-wave, spoke, and elliptical. The low beam current for the CW operation of Project X requires cavities to operate at a high loaded Q and, ... Mehr lesen
