摘要

For optimization and adjustment of ion beam thrusters, knowledge of physical beam parameters and plasma processes in the ion source can be provided by suitable diagnostics. For this purpose, novel – but relatively simple (and cheap) – diagnostic methods which may complete the common diagnostics are suggested. The so-called ”non-conventional” methods are: rn1. axial and radial determination of the ion beam profile by energy flux measurements, rn2. determination of the thrust by visualizing the interaction of the ion beam with a cloud of micro-disperse particles (micro-probes), and rn3. characterization of the sheath region in the ion plasma source by analytical sheath photometry.

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] .
