| Popis: | Beijing free electron laser (BFEL) is a Compton type mid-infrared FEL facility. By using a thermionic cathode RF gun as an injector, 30 MeV s-band RF linac and two wiggler-optical cavity beam lines generate mid- and far-infrared radiation in the wavelength range of 5-50 mum. BFEL facility possesses the conditions for a user's facility. The running is stable, intensity fluctuation of laser is small, and wavelength adjustment is flexible. The stability test showed that the pulse energy fluctuation is about 1% within 30 minutes, and wavelength fluctuation is less than 0.1%. In this year, the lasing time used for users has reached 1600 hours. More than 250 samples have been studied and many application items have been concerned. Five user's stations will be established. Among them, two key experimental stations; FEL spectrum analysis station, and FEL steady state analysis station, have been constructed. For the purpose of user's applications, special equipments have been provided. Some experimental results of the application items are also presented. |
