Computing at the VUV-FEL

Teresa Nunez, Thorsten Kracht, Kay Rehlich

A ''Free Electron Laser'' for wavelengths down to 6nm in the vacuum ultraviolet and soft X-ray regime (VUV-FEL) is under construction at the Tesla Test Facility at DESY (Hamburg). It is operated in the ''self-amplified spontaneous emision'' (SASE) mode and delivers sub-picosecond radiation pulses, with gigawatt peak powers. The VUV-FEL is an international project, where different hardware and software components are provided from collaborating institutes around the world. This requires a common control system, which enables the integration of the different software protocols. In addition to the operation and control of the VUV-FEL, the control system should also satisfy the requirements of the experiments that will make use of this laser facility. From this point of view, it has to provide and store information for the users, allow the integration of hardware and information of the experiments in the general control system, and allow the correlation between experiments and machine/diagnostics information. Moreover, the characteristics of the radiation generated at the FEL (based on the SASE principle) requires the information to be provided and correlated in a single pulse basis (10MHz). A Data AcQuisition system based on DOOCS (a Distributed Object Oriented System developed at DESY) is under development satisfying these requirements.
