Engineering constraints and computer-aided optimization of electrostatic lens systems

Autor: H. W. G. van der Steen, J. P. Adriaanse, J. E. Barth

Publikováno v: Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 298:377-382

An optimization tool for the design of electrostatic lens systems with axial symmetry is presented. This tool is based on the second-order electrode method combined with a multivariable numerical optimization procedure. The second-order electrode met

First step towards application of high-temperature superconductors for planar magnetic lenses

Autor: P. van Zuylen, K. D. van der Mast, J. P. Adriaanse

Publikováno v: Journal of vacuum science and technology. Pt.B., 6, 9, 2866-2869

The feasibility of high-temperature superconductors for applications in particle optics is discussed. Allhough high Tc superconducting coils and wire are not available yet, we conclude that thin films are very promising for ironless magnetic lenses d

A thin film superconducting lens element for electron optics

Autor: K D van der Mast, J. P. Adriaanse, P. van Zuylen, W C Heerens

Publikováno v: Superconductor science and technology, 4, 495-498

The application of high Tc superconductors, especially thin films, for magnetic lenses is discussed. If a thin film is patterned with a spiral, a small coil is obtained which can be utilized as a magnetic lens. However, because of field strength and

Practical optimization of electrostatic lenses

Autor: J. E. Barth, J. P. Adriaanse, H. W. G. van der Steen

Publikováno v: Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures. 7:651

A method for the optimization of electrostatic lenses is presented. It is applied to optimize several three‐electrode lens designs for particular applications. The free parameters of the optimization are the physical quantities describing the shape
