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

Try widening your search to All Fields.

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