Perhaps you should try some spelling variations:
"particle acceleratond" » "particle accelerations", "particle accelerators", "particle acceleration", "particle accelerationd", "particles accelerationd", "particle accelerationsd"
"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"))) OR ("particle acceleratond")))).
• Removing quotes may allow a broader search: (( particle accelerator ) or ((((( particle acceleraton ) or ( particles accelerated ))) or ( particle acceleratond )))).
• Adding a wildcard symbol may retrieve word variants: (("particle accelerator") or ((((("particle acceleraton") or ("particles accelerated"))) or ("particle acceleratond"))))*.
