Status of a THz source based on a FEL | |
|
||
| Abstract THz wave have many special performances so that it will be applied in many field. So far there were many kind of THz Source, one of them is based on a FEL that can produce high power (~kW). This paper will describe the design of a THz source based on a FEL which is consists of a LINAC of 14MeV, undulator and a optical resonance cavities. 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 and so on. The LINAC was installed on November of 2014. Last year, we finished the install of the undulator and the optical resonance cavities. Now the LINAC has been testing and commissioning for THz radiation test. So far, the beam parameters tested of the LINAC are as the following: beam Energy is of 13.58MeV, macro pulse current is of 655mA,μpulse beam current is of 30A, beam macro pulse length is of 1-2's, beam bunch length(μpulse) is of 8ps, energy spread of 0.33% , normal beam emmitance is of 24.1mm.mrad. | ||
