Abstract :
We describe the performance and current status of the electron beam diagnostic complement for Jefferson Lab´s IR-FEL oscillator. In addition measurements for the driver-accelerator are presented. Beam diagnostics devices include optical transition radiation profile monitors, multi-slit beam emittance measurement, coherent transition and synchrotron radiation based bunch length monitors, both strip-line and button antenna BPM´s and pick-up cavities for longitudinal transfer function measurement. All device are controlled via the EPICS control system
