Perhaps you should try some spelling variations:
"particles accelerated" » "particles acceleration", "partially accelerated", "lattices accelerated"
"particle accelerator" » "particle accelerators", "particle acceleration"
"particle acceleraton" » "particle acceleration", "particles acceleration", "particle accelerations"

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