THPHA116	Emittance Measurement and Optics Matching at the European XFEL	1655
	S.M. Meykopff, B. Beutner DESY, Hamburg, Germany
	Electron beam quality described by the emittance or phase space moments are important for the operation of FEL facilities like the European XFEL. For the operation these parameters need to be routinely measured. Based on such measurements machine setup can be optimized to match beam requirements. The beam parameters depend on parameters like quadrupole magnet strength or RF settings. While manual tuning is possible, we aim for highly automatized procedures to obtain such optimizations. In this paper we will present and discuss an overview of the different subsystems which are involved. These include image acquisition, analysis, and optics calculations as well as machine control user interfaces.

Emittance Measurement and Optics Matching at the European XFEL

Electron beam quality described by the emittance or phase space moments are important for the operation of FEL facilities like the European XFEL. For the operation these parameters need to be routinely measured. Based on such measurements machine setup can be optimized to match beam requirements. The beam parameters depend on parameters like quadrupole magnet strength or RF settings. While manual tuning is possible, we aim for highly automatized procedures to obtain such optimizations. In this paper we will present and discuss an overview of the different subsystems which are involved. These include image acquisition, analysis, and optics calculations as well as machine control user interfaces.
