The Free Electron Laser launched at JINR for the first time
On 19 March 2013, in VBLHEP, during a regular run of the electron beam at the test bench of the linear accelerator in building 118 (the Dzhelepov Laboratory of Nuclear Problems site), infrared radiation with the wavelength of 14 micrometres after the permanent magnet undulator was obtained for the first time. The energy of the electron beam was 17 MeV and the current was about 6 mA. The generation effect of coherent radiation by an electromagnetic beam passing a periodic arrangement of magnets with alternating poles (undulator) is called the Free Electron Laser (FEL). FEL is employed in the world for a wide range of applied tasks in biology, materials sciences, solid state physics, nanotechnologies. The work on the start-up of the FEL was implemented by a group of VBLHEP scientists headed by V.V. Kobets and N.I. Balalykin.
