	In November 2013, the FAIR management delegated the responsibility for the technical design, construction, installation, and commissioning of the whole CR and its components from GSI to Budker Institute of Nuclear Physics (BINP). Since that time a lot of modifications of the original design were made aiming to improve the beam parameters and the machine performance. This work shows the present status of the development.

THPSC052	The Longitudinal Broadband Impedance and Energy Spread Measurements at VEPP-4M	650
	V.M. Borin, V.A. Kiselev, G.Y. Kurkin, O.I. Meshkov, S.A. Nikitin, M.A. Skamarokha BINP SB RAS, Novosibirsk, Russia V.L. Dorokhov BINP, Novosibirsk, Russia
	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.

THPSC061	Beam Diagnostics Overview for Collector Ring at FAIR	676
	Yu. A. Rogovsky, E.A. Bekhtenev, M.I. Bryzgunov, O.I. Meshkov BINP SB RAS, Novosibirsk, Russia O. Chorniy GSI, Darmstadt, Germany
	The Collector Ring (CR) is a dedicated storage ring in the FAIR project, where the main emphasis is laid on the effective stochastic precooling of intense secondary beams of stable ions, rare isotopes or antiprotons. A complex operation scheme with several types of operational cycles with beams in CR starting from injection, RF gymnastics, stochastic cooling then, and finishing to extraction is foreseen. Beam parameters changes significantly during the cycles. This demands an exceptional high dynamic range for the beam instrumentation. Non-destructive methods are mandatory for high currents as well as for the low current secondary beams due to the low repetition rate. Precise measurements of all beam parameters and automatic steering with short response time are required due to the necessary exploitation of the full ring acceptances. An overview of the challenges and solutions for various diagnostic installations will be given.

THPSC074	Longitudinal Beam Distribution Measurements in Damping Ring of VEPP-5 Injection Complex	705

	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.
