This Tech Talk briefly outlines the requirements that simulation software must meet to provide useful design information, and describes how these are fulfilled by Opera.
X-ray tubes are widely used in a diverse range of applications and industries, from test and inspection in aviation and food to diagnosis and treatment in healthcare.
These devices rely on the generation of a beam of electrons that is accelerated and focused onto a high atomic number target electrode. The characteristics of the X-rays that are subsequently generated depend on the energy, current and spot shape of the beam on the target, and precise control of these is critical for regulation of such factors as dose rate and penetration factor. Given the ionizing nature of X-rays, this of vital concern in all applications, and particularly so in healthcare.
Opera has the ability to accurately and rapidly calculate electric and magnetic fields, to model complex primary and secondary particle emission and to track particles in combined fields, taking full account of relativistic and space-charge effects. These features have ensured that Opera has enjoyed a leading role in X-ray tube design software for many years.
