Advanced Surface Polishing For Accelerator Technology Using Ion Beams

Insepov, Z.; Norem, J.; Hassanein, A.; Wu, A. T. (American Institute of Physics, 2009-03)

Surface erosion problems are common in the development of TeV accelerators, fusion and fission reactors, semiconductor, optical and magnetic storage devices, and Extreme Ultra-Violet (EUV) lithography devices. We have ...
Modification on surface oxide layer structure and surface morphology of niobium by gas cluster ion beam treatments

Wu, A. T.; Swenson, D. R.; Insepov, Z. (Physical Review Special Topics-Accelerators and Beams, 2010)

Recently, it was demonstrated that significant reductions in field emission on Nb surfaces could be achieved by means of a new surface treatment technique called gas cluster ion beam (GCIB). Further study as shown in this ...
