The University of Wisconsin-Madison's Synchrotron Radiation Center and the Massachusetts Institute of Technology (MIT) are developing a seeded VUV/soft x-ray free electron laser (FEL) serving multiple simultaneous users. The design uses an L-band CW superconducting 2.2 GeV linac to deliver 200 pC bunches to several FELs that cover the 5-900 eV photon range at repetition rates from kHz to MHz. The FEL output will be fully coherent longitudinally and transversely, with tunable pulse energy and variable polarization. To avoid the need for fresh electron bunches, bunch seeding at higher photon energies will be performed with high harmonic generation (HHG) laser pulses. This facility is expected to enable new science through ultrahigh resolution in the time and frequency domains, as well as coherent imaging and nanofabrication.
