Abstract : This report describes the accomplishments of the Working Group on Far Field Accelerators. In addition to hearing presentations of current research, the group produced designs for 100 MeV demonstrations accelerators, 1 GeV conceptual accelerators and a small electron beam source. Two of the 100 MeV designs, and Inverse Free Electron Laser (IFEL) and an Inverse Cerenkov Accelerator (ICA), use the CO2 laser and the 50 MeV linac at the Advanced Test Facility (ATF) at Brookhaven National Laboratory (BNL), requiring only the modest changes in the current experimental setups. By upgrading the laser, an ICA design demonstrated 1 GeV acceleration in a gas cell about 50 cm in length. For high average power accelerators, examples based on the IFEL concept were also produced utilizing accelerators driven by high average power FELs. The Working Group also designed a small electron beam source based on the inverse electron cyclotron resonance concept. Accelerators based on the IFEL and ICA may be the first to achieve 100 MeV and 1 GeV energy gain demonstration with high accelerating gradients.
