Abstract: A final research report of the 10~(11) watt high--power, intense, relativisticelectron beam accelerator system is presented. The indices of this system are asfollow: Peak Electron Energy: 0.8--1 MeV, Peak Current: 150 kA, Beam Energy: 6--9kJ, Beam Spot: 4--10 cm~2, Pulse Duration: 100 ns. The technical data, the structure of each essential parts of the machine andthe experimental results are given. The whole experimental results obtained showthat this system has good characteristics.
