	N.A. Vinokurov BINP SB RAS, Novosibirsk, Russia
	The Novosibirsk ERL is dedicated electron beam source for three free electron lasers operating in the wavelength range 8 - 240 micron at average power up to 0.5 kW and peak power about 1 MW. Radiation users works at 8 user stations performing biological, chemical, physical and medical research. The Novosibirsk ERL is the first and the only four-turn ERL in the world. Its peculiar features include the normal-conductive 180 MHz accelerating system, the DC electron gun with the grid thermionic cathode, three operation modes of the magnetic system, and a rather compact (6×40 m2) design. The facility has been operating for users of terahertz radiation since 2004. The status of the installation and plans are described.

MOCOZBS03	Recent Advances in Terahertz Photonics and Spectroscopy at Novosibirsk Free Electron Laser

	The Novosibirsk free electron laser facility (NovoFEL) operates in the spectral range from 5 to 240 micrometer. High power, narrow linewidth and frequency tunability enable a wide variety of experiments. NovoFEL has eleven user stations open to local and external users. In this paper, we survey selected experiments in photonics performed recently at the facility, such as ellipsometry, holography, surface plasmon polaritons study, pump-probe spectroscopy, and the investigation of the Talbot effect. Additionally, this paper will focus on another field of terahertz (THz) photonics, the transformation of (FEL) radiation into modes different from a Gaussian. Optical elements for intense THz waves differ from classical optical elements. Diffractive optical elements (DOEs) become beneficial for beam manipulation. For instance, in biological experiments a uniform irradiation of substances might be necessary; beams with radial polarization may be required in experiments on the generation of plasmons on wires; pencil-like or "nondiffractive" Bessel beams could be applied to radioscopy of extended objects, etc. A brief overview of THz beam transformations with DOEs will be given. All experiments were carried out using equipment of the Siberian Center for Synchrotron and Terahertz Radiation. The authors are grateful to the NovoFEL team for continuous support of the experiments.

	Continuous wave (CW) 100 mA electron rf gun for injecting the high-quality 300-400 keV electron beam in Novosibirsk Energy Recovery Linac (ERL) and driving Free Electron Laser (FEL) was developed, built, and commissioned at BINP SB RAS. The RF gun consists of normal conducting 90 MHz rf cavity with a gridded thermionic cathode unit. Bench tests of rf gun is confirmed good results in strict accordance with our numerical calculations and showed reliable work, unpretentious for vacuum conditions and stable in long-term operation. The design features of different components of the rf gun are presented. Preparation and commissioning experience is discussed. The latest beam results are reported.

WEPNEC16	Electron Outcoupling System of Novosibirsk Free Electron Laser Facility - Beam Dynamics Calculation and the First Experiments	98

	The radiation power of the FEL with optical cavity can be limited by the overheating of reflecting mirrors. In the electron outcoupling scheme electron beam radiates the main power at a slight angle to the optical axis. For this, it is necessary to divide undulator by a dipole magnet at least in two parts - the first for the electron beam bunching in the field of the main optical mode, and the second for the power radiation by deflected beam. Electron outcoupling system is installed on the third FEL based on the multiturn energy recovery linac of the Novosibirsk Free Electron Laser facility (NovoFEL). It consists of three undulators, dipole correctors and two quadrupole lenses assembled between them. There are two different configurations of the system since the electrons can be deflected in either the second or the third undulator. The electron beam dynamics calculations and the results of the first experiments are presented.

	The Novosibirsk ERL is the first in the world multi-orbit ERL with high average current. It is used as a source of electron bunches for three powerful FEL-oscillators which operate in CW mode. In present configuration the ERL Injector comprises a 300-kV electrostatic gun with thermionic cathode, as well as one bunching and two accelerating cavities separated by the drift space which is used for bunch compression. In near future the new RF gun will be added to this configuration. The basic requirement for the injector is to provide beam parameters necessary for FEL operation. These parameters include bunch charge more than 1 nQ and repetition rate about 10 MHz. Very small emittance and very short pulse duration are not required in our case because of long FEL radiation wavelength and low RF frequency of the main linac. We present detailed description of the injector setup and results of beam parameters measurements. The measured parameters are compared with simulation results. We also discuss future upgrade which includes installation of the new RF gun.
