    "abstract": "The Jefferson Lab (JLab) IR Demo Free Electron Laser (FEL) has completed\ncommissioning and is initiating user service. The FEL - a high repetition rate,\nlow extraction efficiency wiggler-driven optical cavity resonator - produces\nover 1 kW of tuneable light on intervals in a 3-6 micron wavelength range. It\nis driven by a 35-48 MeV, 5 mA superconducting RF (SRF) based energy-recovering\ncontinuous wave (CW) electron linac. The driver accelerator meets requirements\nimposed by low energy, high current, and a demand for stringent beam control at\nthe wiggler and during energy recovery. These constraints are driven by the\nneed for six-dimensional phase space management, the existence of deleterious\ncollective phenomena (space charge, wakefields, beam break-up, and coherent\nsynchrotron radiation), and interactions between the FEL and the accelerator\nRF. We will detail the system design, relate commissioning highlights, and\ndiscuss present performance.",
