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

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 accelerators") OR ("particle acceleraton"))) OR ((("particles accelerated") OR ("lattices accelerated"))))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"particle accelerator\") or (((((\"particle accelerators\") or (\"particle acceleraton\"))) or (((\"particles accelerated\") OR (\"lattices accelerated\"))))))*".
• Removing quotes may allow a broader search: (( particle accelerator ) or ((((( particle accelerators ) or ( particle acceleraton ))) or ((( particles accelerated ) OR ( lattices accelerated ))))))*.
