摘要

A combination of a Hartmann-Shack sensor and a standard far-field measurement on one single detector is proposed. The technique is fast, manages without moveable parts, thus permitting a very compact design. It is not only suited for characterisation of the wave-front distribution, but may also be considered for determination of the important parameters beam width, beam divergence and beam propagation ratio M~2 of partially coherent laser beams. First results indicate that a fairly thorough beam characterisation including spatial coherence, propagation characteristics and beam quality can be achieved with this method.

7. The VUV and soft x-ray free electron laser FLASH (former VUV-FEL) is a user facility at DESY\ud (Hamburg). In order to optimize the performance of the facility, an accurate characterization of the\ud electron beam properties is essential. The transverse projected emittance, one of the important parameters\ud characterizing the quality of an electron beam, is measured using a four monitor method with optical\ud transition radiation monitors. A normalized rms emittance below 2 mmmrad for a 1 nC beam has been\ud measured. In this paper we describe the experimental setup, data analysis methods, and present\ud experimental results. [O] .
