Описание
The ion beam probe characteristics such as, lateral resolution, chromatic aberration and beam current stability are basic requirements for good nuclear microscopy. To be able to deliver ion beams on target with the right conditions for micro analytical work in addition to an optimal object, quadrupole lens and scanning coil set-up, the optimisation of accelerator optics parameters is required to be able obtain adequate operational properties for the ion beam. Recently a new generation of ion accelerating machines, designed for nuclear microscopy are provide with a better microprocessor control over the optics of the accelerator. This on the other hand helps to maintain an optimal beam probe for high resolution at target surface.
