Status of “Siberia-2” SR sourse preinjector
Improvements made in linac systems have significantly increased the reliability of its operation. At present time the linac injects an electron beam with an energy of 75 MeV, beam current of 65 mA (DE/E=1%), with a pulse duration of 18 ns at a repetition rate of 1 pps
Control system of a high-power infrared free electron laser
The control system of the high power infrared FEL is built on the base of a two-level distributed system. The system includes the operator interface at the upper level and Input/Output Controllers under supervision of the real time operating system at the lower level. All hardware for the control system of the FEL is produced by our institute, which solves several problems of hard real time and reduces cost of equipment
Tandem proton accelerator as injector for TRAPP
To inject protons to the TRAPP (synchrotron for therapy of cancer) a tandem accelerator has been constructed. Its parameters are: protons energy is 1.4 MeV, current is 3 mA, pulse duration is 2 μs, frequency is up to 1 Hz. Negative hydrogen ions are extracted through the slit from a magnetron discharge on the heated surface of the LaB6 cathode. The beam of negative ions with an initial energy of 25 kV accelerates up to the half energy in the first accelerating tube, than recharges into protons in gas nitrogen target in a tube at a potential of 700 kV. After that, the proton beam doubles its energy in the second accelerating tube. Operating and control of the tandem are by means of computer
First experimental results obtained using the highpower free electron laser at the siberian center for photochemical research
The first lasing near the wavelength of 140 µm was achieved in April 2003 using a high-power free electron laser (FEL) constructed at the Siberian Center for Photochemical Research. In this paper we briefly describe the design of the FEL driven by an accelerator–recuperator. Characteristics of the electron beam and terahertz laser radiation, obtained in the first experiments, are also presented in the paper.У Сибірському центрі фотохімічних досліджень навесні 2003 року отримана генерація випромінювання з довжиною хвилі 140 мкм на потужному лазері на вільних електронах (ЛВЕ). У роботі коротко описана конструкція ЛВЕ на базі прискорювача рекуператора і представлені результати вимірювання деяких параметрів електронного пучка і терагерцового випромінювання.В Сибирском центре фотохимических исследований весной 2003 года получена генерация излучения с длиной волны 140 мкм на мощном лазере на свободных электронах (ЛСЭ).
