Abstract
With the rapid development of the 4th generation high-energy synchrotron sources and X-ray free-electron laser facilities, wavefront preservation is put forward as a new challenge in compound refractive lenses (CRL) for beam transport. More sophisticated measurements are required for characterizing the performance of CRL. In this study, different methods are used to measure the misalignment and surface errors of bi-concave lens including confocal laser microscopy, X-ray speckle vector tracking, and computer tomography. The effects of the misalignment and surface errors on focus profile were also simulated based on physical optics.
期刊介绍:
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
