Isotrajectory dynamics as a new field of corpuscular optics

摘要

The paper presents a new approach to corpuscular optics - isotrajectory corpuscular optics - that can remove many principal limitations inherent in optics of static systems. The freedom from the limitations makes it possible to develop novel corpuscular-optical elements for pulsed flows of particles with much better or even unique performance parameters. The isotrajectory lateral differential ivnariant that is similar to Helmholtz-Lagrange invariant for static corpuscular-optical systems has been derived. The concept of space and time aberration (STA) and its computation algorithms are considered. Possible applications of STA in corpuscular optics is discussed.
