Commissioning the compact LINAC of 14Mev for a THz source based on FEL Y.J.Pei National Synchrotron Radiation laboratory, University of Science & Technology of China Abstract The compact LINAC of 14MeV is designed for a FEL which will produce a THz radiation through 30μm to 300μm. The LINAC was composed of a novel EC-ITC-RF gun, constant gradient travelling wave accelerator with a collinear absorbing load, focusing system, RF power system, beam diagnostic system, vacuum system, control system

Now the LINAC has been testing and commissioning for THz radiation test. So far, the running beam parameters of the LINAC are as the following: Energy is of 13.58MeV macro pulse current is of 655mA macro pulse length of 1.2μsμpulse beam current is of 59A beam length of theμpulse is of 4ps energy spread of 0.33% normal beam emmitance is of 24.1mm.mrad.
