Perhaps you should try some spelling variations:
"particle acceleration" » "particle accelerators"
"particle accelerator" » "particle accelerators"
"lattices accelerated" » "matrices accelerated", "particles accelerated", "devices accelerated"

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (((("particle accelerator") OR ("particle acceleration"))) OR ("lattices accelerated")).
• Removing quotes may allow a broader search: (((( particle accelerator ) or ( particle acceleration ))) or ( lattices accelerated )).
• Adding a wildcard symbol may retrieve word variants: (((("particle accelerator") or ("particle acceleration"))) or ("lattices accelerated"))*.
