Description
A 40MeV electron beam, using the inverse free-electron-laser interaction, has been accelerated by ΔE/E=2.5% over a distance of 0.47m. The electrons interact with a 1 endash 2GW CO2 laser beam bounded by a 2.8mm i.d.sapphire circular waveguide in the presence of a tapered wiggler with Bmax≅1T, and a period 2.89≤λw≤3.14cm. The experimental results of ΔE/E as a function of electron energy E, peak magnetic field Bw, and laser power Wl compare well with analytical and 1D numerical simulations and permit scaling to higher laser power and electron energy. copyright 1996 The American Physical Society
