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 ...
Breakdown in RF cavities

Norem, J.; Hassanein, A.; Insepov, Z.; Konkashbaev, I. (Proceedings of 2005 Particle Accelerator Conference, Knoxville, Tennessee, 2005)

We present a simple model of breakdown in rf cavities. For most events this involves tensile stress and tensile strength, however other effects can also contribute. We discuss the effects of different materials, fatigue, ...
Radiation-induced synergistic effects of athermal and thermal mechanisms on erosion and surface evolution of advanced electrode and condenser optics materials

Allain, J. P.; Hassanein, A.; Burtseva, T.; Yacout, A.; Insepov, Z.; Taj, S.; Rice, B. J. (Proceedings of SPIE, 2004-02)

In extreme ultraviolet lithography (EUVL) environments transient plasma dynamics dictate conditions for particle/surface interactions. A critical challenge facing EUVL development is optic component lifetime both in ...
The Interactions of Surface Damage on RF Cavity Operation

Norem, J.; Bross, A.; Hassanein, A.; Qian, Z.; Yoon, K. E.; Moretti, A.; Li, D. (Fermilab, 2006-06)

Studies of low frequency RF systems for muon cooling has led to a variety of new techniques for looking at dark currents, a new model of breakdown, and, ultimately, a model of RF cavity operation based on surface damage. ...
