Experiments on removing nano particles on a substrate using a supersonic particle beam

Lee J.W., Lee M.J., Lee J.W., Lee M.J., Yi M-Y, Pohang University of Science and Technology, KR

Cryogenic particle beam can be an effective means of removing nano-sized contaminant particles from a substrate surface. In order to generate a particle beam of high intensity and controlled size and temperature, Argon gas was [...]

Electromechanical System for Lorentz Force Compensation

Sekalski P., Napieralski A., Simrock S., Technical University of Lodz, PL

The cavity is the main element of each linear accelerator used for high-energy physics purpose. The resonant frequency of cavities depends on its shape. Due to the pulse operation they are deformed by dynamic Lorentz [...]

Simulation of Aluminum Micro-mirrors for Space Applications at Cryogenic Temperatures

Kuhn J.L., Dutta S.B., Greenhouse M.A., Mott D.B., NASA/Goddard Space Flight Center, US

Closed form and finite element models are developed to predict the device response of aluminum electrostatic torsion micro-mirrors fabricated on silicon substrate for space applications at operating temperatures of 30K. Initially, closed form expressions for [...]
