What does Opera display in terms of ion beam statistics?
Why are charged particle solutions iterative?
Can Opera model Magnetron Sputtering?
What is meant by Secondary Emission?
Can Opera calculate the temperature rise due to the impact of kinetic charged particles onto a surface?
For analysis of a conventional space charge limited, tungsten cathode, triode gun, which do you suggest is most appropriate emission model?
In an accelerator magnet, magnetic fields are used to steer and focus charged particle beams. What tools does Opera have to rapidly assess field quality? And can I see how the particle beams behave?
• 3D track lines through the geometry
• projections onto the major coordinate planes
• intersection points on any 2d plane
• current or power density maps
Can Opera model pulsed magnets, especially the redistribution of currents in the conductors? And how does it deal with laminations?
What physics can Opera capture in the superconducting windings of my magnet?
How accurate is Opera for simulating NMR/MRI magnets?
I’m designing superconducting solenoid MRI magnets and need to assess the small effect of the shielded room and the steel reinforcing on the magnet’s homogeneity?
Can I assess how effective the shielding is for my proposed MRI facility?
Can I calculate a Torque-Speed curve for my Synchronous Reluctance Machine?
Can you display a Gorges Diagram for my electrical machine?
Can Opera analyse my electrical machine under fault conditions?
How do I account for demagnetization of my permanent magnets in my electrical machine?
Can I look at magnetization of my permanent magnets before they are assembled into my electrical machine?
Can Opera calculate the losses in my machine?
Copper losses can be calculated simply from the current flowing in simulated windings.
Hysteresis losses including rotational component losses can be explicitly obtained using the hysteresis solver and eddy current losses by explicitly defining the materials’ conductivities.
Any loss quantity can be used as a heat source in thermal analyses.
Can you consider both Electromagnetic and Structural performance of a Synchronous Reluctance (SynchRel) Machine at the same time, or do I not need to?
Can Opera model Superconducting Generators; do you have any experience in this field?
Normal operation is one thing, how about performance under fault conditions?
Can Opera analyse a transformer under open-circuit, short-circuit and inrush conditions?
Can Opera use my full hysteresis curve for my soft magnetic material?
