SRF electron guns hold out the promise of very bright beams for use in electron injectors, particularly for light source applications such as Free Electron Lasers. The University of Wisconsin is midway in a multi-year program to demonstrate a low frequency electron gun based on a quarter wave resonator cavity. The design includes active tuning and a high temperature superconducting solenoid for emittance compensation. We will report on the status of the 4 MeV SRF electron gun, including the cryomodule, the RF power coupler, the main RF power amplifier/low level RF control system, the photocathode laser system, and the diagnostic beamline. Installation is moving forward in a recently renovated experimental vault adjacent to the existing Aladdin synchrotron. First electron beam is expected in the summer 2012.

  The University of Wisconsin-Madison is continuing design efforts for a vacuum ultraviolet/X-ray Free Electron Laser facility. The design incorporates seeding the FEL to provide fully coherent photon output at energies up to ~1 keV. The focus of the present work is to minimize the cost of the facility while preserving its performance. To achieve this we are exploring variations in the electron beam driver for the FEL, in undulator design, and in the seeding mechanism. Design optimizations and trade-offs between the various technologies and how they affect the FEL scientific program will be presented.
