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

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 accelerate") OR ("lattices accelerated")))).
• Removing quotes may allow a broader search: (( particle accelerator ) or ((( particle accelerate ) or ( lattices accelerated )))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((("particle accelerate") or ("lattices accelerated"))))*.
