It is used for spectroscopic investigations of molecules, clusters, nanoparticles and surfaces. The oscillator FEL is operated with 15 - 50 MeV electrons from a normal-conducting S-band linac equipped with a gridded thermionic gun and a chicane for controlled bunch compression. The EPICS software framework was choosen to build the control system for this facility. In an effort to support the various experimenters two different Laser Beam Profiling cameras have been integrated. Here, the areadetector framework with genicam integration is used. The control system was also expanded with fast digitizers (SIS3316) but connected via Ethernet instead of using a VMEbus crate controller to get a higher flexibility. A iPad app for monitoring completes the enhancement. This paper presents design and implementation aspects of the upgrade, its capabilities, and lessons learned during the development.
