Field Precision has posted over 20 PDF tutorials on finite-element techniques for practical applications in electromagnetics and X-ray science. The articles are of interest to to students and researchers.
Current topic areas include the following:
* Electron gun design
Design procedures for high-current, converging-beam guns. Variable current injectors for linear accelerators. Simulation of intense beam pinches for pulsed radiography. Equations and algorithms for emittance calculations.
Modeling cathode temperature effects. 3D design of sheet-beam electron guns
* Magnetic fields
Design of high-uniformity, energy-efficient solenoids. Force calculations for pull solenoids and other devices. Theory and applications of the Maxwell stress tensor. Magnetic shield design
* Electrostatics and high voltage
Effect of surrounding structures on electric field levels on high-voltage insulators. Calculating mutual capacitance of a multi-electrode systems via the energy method.
* X-ray science
Finding resolution limits in X-ray imaging systems.
* Microwave and RF
EMP generation by pulsed dipole radiators.
New tutorials are continually being added to the Technical Library at http://www.fieldp.com/library.html. The library also includes downloadable instruction manuals in PDF format for all Field Precision programs as well as reprints of recent journal publications from the company.
