	Funding: This work was supported by Russian Science Foundation (project N 14-50-00080). High-power free electron laser (FEL) facility NovoFEL has been created at Budker INP. Its wavelength can be tuned over a wide range in terahertz and infrared spectrum regions. As a source of electron bunches this FEL uses multi-turn energy recovery linac which has five straight sections. Three sections are used for three FELs which operate in different wavelength ranges (the first one - 90-240 microns, the second - 37-80 microns and the third - 5-20 microns). The first and the second FELs were commissioned in 2003 and 2009 respectively. They operate for users now. The third FEL is installed on forth accelerator track which is the last one and electron energy is maximal here. It comprises three undulator sections and 40 m optical cavity. The first lasing of this FEL was obtained in summer, 2015. The radiation wavelength was 9 microns and average power was about 100 watts. The designed power is 1 kilowatt at repetition rate 3.75 MHz. Radiation of third FEL has been delivered to user stations recently. The third FEL commissioning results as well as current status of the first and second FELs and future development prospects are presented.

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 the calculations. The gun was tested up to the design specifications at a test bench that includes a diagnostics beam line. The rf gun stand testing showed reliable work, unpretentious for vacuum conditions and stable in long-term operation. The design features of different components of the gun are presented. Preparation and commissioning experience is discussed. The beam test results are summarized.

	VEPP-2000 is electron-positron collider exploiting the novel concept of round colliding beams. After three seasons of data taking in the whole energy range of 160-1000 MeV per beam it was stopped in 2013 for injection chain upgrade. The linking to the new BINP source of intensive beams together with booster synchrotron modernization provides the drastic luminosity gain at top energy of VEPP-2000. Recomissioning status, fist results and perspectives of the VEPP-2000 complex will be presented.

THPSC052	The Longitudinal Broadband Impedance and Energy Spread Measurements at VEPP-4M	650

	The paper presents studies of the longitudinal broadband impedance of VEPP-4M and measurements of its bunch energy spread at different energies in range of 1.45 - 3.5 GeV. In order to measure the longitudinal bunch size at different currents we used PS-1/S1 streak camera with picosecond temporal resolution. Considering that influence of collective effects is negligible at low currents we determined bunch energy spread from its length at low currents. Collected bunch length data demonstrate microwave instability thresholds and potential well distortion lengthening. Potential well distortion was studied at 3 GeV and 3.5 GeV. Measured potential well distortion lengthening was used to estimate a value of the reactive part of the longitudinal impedance. Observed microwave instability thresholds was used to measure the value of broadband impedance. Measured value of the VEPP-4M is 7.9 ± 1.5 Ohm.

	Injection Complex VEPP-5 was turned into operation in the end of 2015 in the Budker Institute of Nuclear Physics (Novosibirsk, Russia). The main task of the facility is production, acceleration and transportation of high intensity electron and positron beams for two BINP's colliders. Now, VEPP-5 successfully delivers electron and positron beams to the collider VEPP-2000 and ready to start operation with the acceleration complex VEPP-4M. Beam diagnostics issues are very important for VEPP-5 facility tuning during the operation. Longitudinal beam diagnostic based on synchrotron radiation in the VEPP-5 Damping Ring is presented in the article. Equipment operation principle, main measurement results and future prospects are presented in this paper.
