  Abstract THz wave have many special performances, such as it can penetrate deep into many organic materials without the damage associated with ionizing radiation such as X-ray, it can be used to distinguish between materials with varying water content, because THz radiation is absorbed by water. In part researchers lacked reliable sources of THz, so develop new THz sources is important now. So far there were many kind of THz Source, one of them is THz source based a FEL that can produce high power (~kW). This paper will describe the design of a LINAC of 14MeV which is used for FEL to produce THz radiation. The LINAC is mainly composed of a novel EC-ITC RF gun, compensation coil, constant gradient accelerating structure, beam diagnostic system and so on. Main design parameters are as following: Energy 7~15MeV Beam current (macro pulse) 571mA (micro pulse) 30~40° Bunch length 5~7ps Charge per bunch 200~300pC Normalized emittance ≤10mm.mrad Energy spread(rms) ≤0.5%

  A 40kW RF Solid State Amplifier (SSA) will replace the 25kW tetrode amplifier as the new RF power generator of HLS 800MeV electron storage ring. This SSA contains sixty-five 650W amplifier units (one unit drives sixty-four’s), with two-stage combination to reach the 40kW output. All of the components of SSA are prepared and tested, each of them meets the design requirements. The SSA has been assembled, and is in off-line testing now. The process of SSA’s design and manufacture, and the test results are presented in this paper.
