Curtain effect free(CEF) is a new CP method for heterogeneous materials.

CP is a commonly-used tool for cross-section sample preparation with ion beams. How to avoid structure deformation during preparation, especially for heterogenous materials, is a task. MSS delivers a new CP method, CEF, to decrease such effect as low as possible.


  • ▪ Wider observation area than CP
  • ▪ Reducing curtain effect
  • ▪ Pristine surfaces can be preserved
