The Help menu

This is an exceptionally comprehensive and easy-to-use on-line Help system.

There are more than 1800 headings in the ‘search’ menu and more than 27000 lines of information.

This is an exceptionally large amount of information and is almost as good as a text book on charged particle optics.

The Help system is easily accessed at all stages of a simulation.

As well as the main search menu the following headings are available on the opening page:
