Penning ion trap is a device used for three-dimensional confinement of ions for high precision nuclear and atomic physics studies. In a Penning ion trap, superposition of a strong homogeneous magnetic field and a weak quadrupole electric field confines the ions in a very small region. The uniformity and stability of magnetic field determines the confinement duration. An electromagnet has been ...

Uterine contractions during pregnancy are currently poorly understood – experts disagree on the mechanisms by which contractions propagate through the organ and the structural layout of the uterine muscle fibers. We have developed a multi-scale model of the uterus, at the cellular, tissue, and organ levels. By comparing simulated abdomen-level magnetic field readings from our model to clinical ...

Two-generation superconducting coils carrying large current in alternating magnetic fields is very common in electrical applications such as HTS linear motor. So it is meaningful to study the characteristics of coated superconductors in the presence of travelling magnetic field. In this paper, by using the finite element simulation software COMSOL Multiphysics® software, the characteristics of ...

The most popular means of depression treatment are psychotherapy, antidepressant medication and recently adopted transcranial magnetic stimulation (TMS) of the human brain. To overcome their disadvantages we are investigating an application of low-field magnetic stimulation (LFMS) to depression treatment. The 3D electromagnetic model of LFMS has been developed. It employs 8 small coils disposed ...

In this paper an attempt has been made to design and analyze integrated circuit interconnects for unshielded four conductors with three levels system using Finite Element Method (FEM). The computational and simulation work has been carried out with help of COMSOL Multiphysics software. We illustrate that FEM is as accurate and effective for modeling multilayered multiconductor transmission ...

Introduction: This study aims the optimization and sensitivity analysis of an existing device. A Secondary Ion Mass Spectrometer (SIMS) device is to be equipped with a high power laser in order to increase sputtering speed. The modified device must be capable of handling the increased level of contamination and energy spread of sample ions. Use of COMSOL Multiphysics® software: Transmission ...

We have used COMSOL Multiphysics® software to design a micropipette for single -cell gene expression profiling. The micropipette design allows us to insert it into a single-cell to extract genes through dielectrophoresis. As dielectriphoretic force depends on the applied electric field (E) and its gradient (∇E^2), we have successfully used COMSOL to calculate E and ∇E^2 in the vicinity of the ...

Two different Finite Element Method (FEM) models of the CANDU® nuclear fuel channels were compared against experimental data to determine if the curvature of the fuel channels is necessary to consider for measurements of the pressure tube to calandria tube gap. The different models were compared against experimental measurements under variations in the wall thickness of the pressure tube. For ...

The lamination of substrates with thin coatings is commonly used in furniture, automotive and avionic industries. In the lamination process the hot melt adhesives are widely used and typically activated at temperatures from 80°C to 140°C by resistive heating. This requires a heat transfer through the coating and/or the substrate. To make the process more flexible, to decrease its energy ...

This elaboration presents a pre-study on automatic rotor construction for the flywheel energy storage system dedicated to operate in the levitation mode. The optimization profile model is used as a basic profile source. The 3D flywheel shape is generated on the base of obtained profiles. Eigenfrequencies are calculated to validate the operation on rigid mode. A steel and aluminum based ...
